Banknote Database Software

Does anyone track their collection using Data Tracker for Currency from
Datavillage.com?

Have you experienced in stability problems with the software once database
exceeds 500 or so records? My records contain lots of images and additional
text - not sure if that's part of the problem?

Anyway database keeps getting wiped. Just disappears. It's not like it's
there and you just can't access it - its gone. Means taking backups every time
you enter a few records - real pain in the...

Anyone else having this problem and are you getting any satisfaction from the
supplier in terms of getting it sorted?
