MBAM_ERROR_LOAD_DATABASE (0, 53)

[techweenie]

I am trying to run malwarebytes on a windows xp embedded client. It installs fine, but every time I try to run it I get the error MBAM_ERROR_LOAD_DATABASE (0, 53). I have followed the instructions in other threads on how to completely remove and reinstall it, but that did not help. I also tried manually deleting the database and letting it download a new one which did not work. The client I'm installing this on has a history of getting infected with malware, but, as far as I have been able to determine, it is clean now. It is not possible to reload the system because it is from a 3rd party vendor.
