[quote:a6qq8pw5]This is one of our biggest releases ever, with the most changes - exercise usual caution if you have projects you are worried about (back them up, or wait a few days to ensure there arent any new bugs).
Sorry, theres not a lot that can be done - I think you've learnt the hard way about backups! .cap files have never been backwards compatible, only forwards - there are usually subtle under-the-hood file format changes and we do some jiggery pokery to make old files automatically import. Still, that message could be friendlier...
