I just downloaded and purchased iCash v.3 (v1 to v3 uprade). I opened my file, and OK'd conversion as asked, but it opened with all the transactions missing.
I tried opening an older backup I had made to the desktop to make sure I had a copy before getting v.3. I used v.1 (so I didn't have to convert it and take a chance of losing my transactions again). There was no problem opening it and all the transactions were there - but not up to the current date of course.
Each time I tried to open a backup file with v.3 I lost my transactions. But when I tried to open the CURRENT file with v.1 - OR the current automatic backup generated by iCash (as recomended by the site administrator) - it said "fatal error opening [accessing?] data"
The last few times both the old and new (converted) data bases have the message "Error updating database schema (Internal error.) Contact Maxprog support". This ALSO includes trying to open the backup copy generated by iCash. At this point I had almost run out of backups and didn't want to lose my transactions by using v.3 again.
