oclHashcat-lite crash

[Mugzy]

When I try to do anything that uses my GPU, I just get the generic "oclHashcat-lite64.exe has stopped working".

It runs fine if I just ask for the help text, but if I try to run a benchmark or process some hashes, I get the crash. Same thing happens in plus if I try to process any hashes.

System Details:
CPU i5-3750
GPU: radeon 7950 3GB
Memory: 16GB
OS: Windows 7 64b

Here are the crash details given by windows:

Letting it debug in VS gives me:
