AssArray save and load

Hi everyone. I coded the AssArray to load and save my game. Works perfect with pressing S and L. I used AppDrive$+AppDir$+"GB.dat"

Just for jun, I loaded the game into a my Win98SE, 300MHZ workstation. Went to press S to save and received a Kernel error. Tried changing it to Apppath$ and still got the error. The game itself runs ok on the old computer, of course slower.

I used WinXP 2.8Ghz to program the game. Bld247.

Have any thoughts why I get the kernel error?

Thanks
