[SOLVED] Vista Unhandled Exception

from Stardock Forums
I can't seem to load any new themes into LogonStudio Vista.  When I click the "Load" button and choose the file to load, I get an error message, shown below.  I can click "Continue" and everything still works, but still nothing loads.  Dragging and dropping does the same thing.  Double-clicking brings up a "LogonStudio Vista has stopped working" window; the app never shows up.  I tried reinstalling, with no success.   Any thoughts?

Yep; I enter admin credentials as the UAC prompt that shows up when I run it.

Apparently logon theme files are encrypted. Why this is I don't understand, but that was part of the cause. I had enabled FIPS compliance on my machine, which essentially mandates a minimum strength of encryption, and LogonStudio doesn't use that hard core of an encryption scheme, causing the program to throw a fit. The support people pointed me here to see if FIPS compliance is enabled. If you don't have a problem disabling FIPS compliance, disabling it should fix this problem. It did so for me, anyway.
