Bert,
I may be wrong, but I think your problem is your moving of files on the computer. The 7000 needs a control file to properly load data. This is included when editing on the 7000 or, I am told, using Techmanager7000 software to edit.

I had similar problems using the computer to edit files. I now do everything on the 7000 with no problems but it is much slower.

This topic was discussed by Alec and others on this forum. A search should give you the answer.

I look forward to Alec's new book on the 7000 so that I will have a better understanding of the 7000 system and will probably order the Techmanager7000 Software at that time.

cheers,

Fran in Florida
