Hello Mario
Thanks for the quick new version, what does eliminate the pack-n-go - problem.
Downloaded and installed here without any problems.
I did then a "Database Diagnostics" inside IMatch (Database Tools), then a "compact and optimize" and finally a "pack & go", where IMatch is closed.
In pack & go I choosed "diagnostics" and "compact" both.
It ended perfect, no error, all seems to be ok again.
Thanks for your quick effort!
