I recently bought a license and I can't activate it When I try to activate it, 2 messages pop up: (1)"Unable to contact license server. Check your proxy settings or contact your system administrator for help." (2)"Installation_token Not Found" "Do you get the same result more than once if you follow the same steps? Y/N" - Yes. I've added screenshots of the messages. I've tried the link that I've seen around these forums - https://keystone.mwbsys.com and it wont load it properly and say - This site can’t be reached keystone.mwbsys.com refused to connect. Try: Checking the connection Checking the proxy and the firewall ERR_CONNECTION_REFUSED Check your internet connection. Check any cables and reboot any routers, modems, or other network devices you may be using. Allow Opera to access the network in your firewall or antivirus settings. If it is already listed as a program allowed to access the network, try removing it from the list and adding it again. If you use a proxy server… Check your proxy settings or contact your network administrator to make sure the proxy server is working. If you don't believe you should be using a proxy server: Go to the Main menu > Settings > Change proxy settings… > LAN Settings and deselect "Use a proxy server for your LAN". And when I try it from my mobile phone it says "OK". I've tried disabling my firewall (Windows firewall) completely and it didn't work either. I've tried opening a hotspot from my mobile phone and connecting to the link I mentioned above through that connection and it still didn't work. When I tried going to the link https://keystone.mwbsys.com while using the built-in vpn in my Opera browser (set to optimal location - I checked the location and it was SWEDEN) It actually showed the "OK" message. I'm on OS WIN10-64, My current browser is Opera GX Thanks alot in advance, S. mbst-grab-results.zip

I had ran a rootkit scan got 3 winzips. I removed these and after doing so malwarebytes has been having problems contacting the license server, it asks me to check my network settings. I could restore them but i have read their are no necessary rootkits for malwarebytes to run and this only happens on one of the two computers i have malwarebytes installed on.

I noticed my performance chugging and saw that MBAMService.exe started overusing my resources. It happens whenever I start up now. Then when I tried to go to My Account, I get a popup saying "Unable to contact license server. Check your network settings or contact your system administrator for help." Windows Defender is disabled. I've ran FRST and MB-Check attached the results file. mb-check-results.zip

Hi guys, I've just bought and downloaded Malewarebytes 3.2.2 and when I went to activate my code. I got this error message. "unable to contact license server. check your network connection or contact your system administrator for help". my internet connection is perfectly fine. Also after i press ok I get another error message saying, "(MBAM404101) Installation token not found. there is a problem with your license key and we are unable to activate your license. please check your license details and try entering your key again". If you can help me I would really appreciate it. Thank You, Avery

So I recently upgraded to MBAM 3.1.2 and ever since then I've tried to click on my license and it shows some error message saying "Unable to contact license server. Check your network connection or contact your system administrator for help". I am my system administrator and I have no clue how to fix this issue. I've tried reinstalling and it didn't work. I didn't recieve this issue back in the 3.0.6 update (i think it was) Please help -Sam
