DOS Program Stops Working After Re-installed

Help!

My DOS Program (Dbase,written in Clipper 3x) stops working after I re-installed Win95. It returns this error message each time I try to run it:

"Run-time error R6003
- integer divide by 0"

Any ideas??

Thanks in advance.

you probably lost files= in config.sys with the reinstall. see if you have a config.old & copy the statement into config.sys
