x64 executables crashing.

I recently received a bug where STEMCalc IV would crash. It was Release 4.2, which I tried out and worked perfectly well on a 32-bit machine. I didn't know what architecture the bug was spotted on, but just now, I've tried running Release 4.2 with the latest patch and it crashed on a 64-bit machine. Of course I downloaded the x64 version of the program, but since I was only able to test on 32-bit systems before, I didn't know about this crash issue. And this issue seems to persist in every singlex64 executables. I'm very sorry for this inconvenience, but luckily, since users with 64-bit machines can run 32-bit executables, users can simply download the latest 32-bit patch for your version or download the full 32-bit release, either way works because this is the problem with the executable. Once again, I'm so sorry for this inconvenience. I'll try to find a workaround and re-upload all patches and releases in 64-bit versions.

All the best,
