Spirit have updated to a new version which fixes a couple of problem.

From their website:

Update (May 3): I’ve updated the jailbreak tool. It no longer deletes photos (sorry!) and should resolve the issue with error code c0000005. (If you still get that error with the new version, try setting compatibility mode to Windows 95.)

You can download it from:
Spirit (Windows)
Spirit (Mac)
