Thanks for the reply and for checking the log file. Yes, that is what I am seeing. Thanks for confirming my product is working. I do hope Malwarebytes looks into why I received that "ID and Key Not Correct" message. I noticed that there is the following message in the confirmation email after purchasing the premium version: ------------ Important: Please make sure you are COPYING and PASTING the ID and Key directly from the confirmation email into the proper fields. The code is case sensitive and contains letters and numbers that can easily be confused, so make sure you distinguish between the letter "O" and the number "0" if you enter the code manually. Also, be careful when pasting that there is no space at the end of either the ID or Key ------------ The need to include that notice is an indication you may have had an inordinate number of users indicating problems with activation. It's understandable that you may initially suspect user typo errors. But I urge you to consider that maybe a large number of those activation problems were not in fact user errors in cut and paste or typing. I offer this as constructive criticism, not whining. I have owned and promoted Malwarebytes since I first learned about it, installed it and purchased the upgrade. I hope your 'exploits' software proves to be as great as your original malware product. One thought, and it's only a wild one. I downloaded and installed the exploits software. Then, because I've been so pleased with your Malwarebytes product, without further ado went ahead and tried to upgrade and purchase the premium version. In the process of purchasing, it showed a download button. I'd already installed it, but figured the premium would be a different download (there was no indication that the premium purchase simply involved an unlocker). So I clicked the download button presented during the purchase process. It turned out to be exactly the same, but I chose to overwrite the original file and download the 'new' file. I then re-installed using the newly downloaded version. I tell you all of this, because I'm thinking maybe the original version had some sort of hook for a key to unlock. but then I installed a new file (although the same version of software). But maybe somehow with the two different installs amidst a purchase, that has something to do with why I got the wrong Key and ID message. Anyway, don't assume the users are doing typos. It was a very frustrating start for me and the problem was that false error message. Please fix it so you don't loose customers.
