The essence of the following. The program on FoxPro 2.6 under DOS. In Windows 98 works without problems. In Windows XP when opening *.dbf file the error message "Not a database file".

Additionally:
1. multiplayer mode
2. the message is issued for files of large size,
3. appears not always, the pattern is not established (sometimes works fine).

Settings are all set.
The suspected title, number of actual records is not equal to the header.

Can someone faced with similar? How to solve the problem?
For earlier thanks to all.
