OpenAccess Express causes compile errors and crash

I am using Visual Studio Professional 2008 Trial Edition,
and have OpenAccess Express installed.

Everything seems to have installed fine.
I created a test project and enabled OpenAccess, generated my classes,
but when I build my test project,
I get compile errors "System.Cryptography.CryptographyException: Access is denied.".
I just get a glimpse of this error, because then Visual Studio crashes.

This does not happen if I set then Encance property to false.
I tried to enhance the .exe manually with VEnhance, supplying correct parameters, but the command prompt gives me these same errors.

I have fiddled around with every possible project setting and security settings, but nothing seems to work.
Is it possible this is happening because I have a trial edition of Visual Studio?

Hello Oli Fribba,
We have just fixed this. If you go to the express download page again there is a custom builds link. Please follow it and try the latest version.

Best wishes,
