W2k8, Sybase Driver, Permissions

Trying to get a .net (32bit) app running on a Windows 2008 server. My experience in the Windows world is quite limited...

Is this related to the Full/Medium trust settings? Windows error logging is pure nonsense :(((

Have been Googling for quite some time. Appreciate your feedback!
