With all the zeros, it looks like what programmers call a NULL dereference. This is a programming error. You really can't "fix" it, it's a problem in the code. Unless you're a programmer and have the code for the program, there's not much you can do.

There's a very small chance this is due to corruption someplace. Maybe there's a bad block on a disk, or a bad entry in the Registry is causing this, and a reinstall will help. But it's unlikely.

I'd check for updates for your program. See if they've fixed the bug. If not, reinstall, in the < 1% chance this will help, but you have no real other tools to try.

MadExcept is a great tool to track down this kind of troubles precisely.

Possibly, you need to run your software inside something like "DOS emulator".
