Solved!!!
Many thanks to Byron Marrowuin, Ed Rauh, Roi Ledford, Evan Delay, Roxanne Seibert, Nancy Folsom and Bonnie Beret.
Solution:
=========
1. With CM repair I get "invalid block at recno 17", tried to fix it but the error follows many times in other blocks.
2. After a suggest of Bonnie and Nancy :), I tried to use the vcx and copy to a dbf, but GPF error.
3. After a BROWSE on cinsoft.vcx I can see:
#17 WINDOWS _RYT0UC3B3 625373530
#18 WINDOWS _RYT0UEA6I 625373530
#19 COMMENT RESERVED
...
4. Without the Hackers Guide, I suppose this must be an entry of a single class, them I do the following code:
USE cinsoft.vcx
COPY NEXT 16 TO part1
GO 20
COPY NEXT 9999 TO part2
USE part1
APPEND FROM part2
COPY TO okey.vcx
5. Now packs, compiles an all! but I looked wich class I lose, and in the class browser didn't see any differences, I review all.
Conclusion
==========
I will make backups more often!!! :)))
Many thanks for your support and help.
