Did you make a backup of your project and library files before you reinstalled? Unfortunately, reloading the program, (unless you chose the custom option to install only selected files) overwrites existing library files causing all place and source data to be lost.
I don't know why so many people think that when they have a problem they should "reinstall" the program. This causes people more problems in the long run. Even using the custom install option is rarely needed. If folks would use the FIXME.BAT and the CHECK/REPAIR utilities, more items could be repaired in an easier manner.
The foxpro error is another subject. If you look down on some of the older messages, or do a subject search on this board for foxpro, you will find further on it.
