[Dxbase] Problem Opening DXBase

Wed Jan 1 10:27:09 EST 2014

I have two calls in DXBase, mine and the Clubs Call.
When I close one and try to open the other, I get an
error message:
Windows - No Disk
Exception Processing Message c0000013 Parameters 75b6bf7c
4 75b6bf7c 75b6bf7c
It takes several attempts to close the Error Message pop-up. I
then need to exit the program and re-open it (the same call) and
then it works fine.
Any thoughts about what is happening ? Would a fresh install of
DXBase help ? Other than the .mbd files, what else should I save ?
Tnx es HNY, Dick, W1KSZ
