Funny, posting a warning about something which clearly is a user error, to begin with. I also don't get why it should be a problem, one should always have a current backup!

A few points.
1. Blaming the customer? Good businesses in the US don’t do that. Try to learn that lesson. It’s invaluable.
2. I have two back ups, one on site and one off site. That was NOT the issue. I had no idea where the catalogs for Capture One were stored. The location of Catalogs in Capture One is not obvious, at least to me, as it is with Lightroom.
3. If a v. 10 compatible Catalog was created as a backup when I opened v. 11, which created a new Catalog that was just compatible with v. 11, I would have thought that the v. 10 backup Catalog would have opened when I clicked on v. 10 to use v. 10. This may all be clear to someone with a deeper understanding of what’s going on under the hood with C1, but many of us don’t and don’t want to learn. We are photographers who want user friendly software and hardware.
4. This could easily have been averted with a clear warning, or, if you don’t like warnings, an “explanation”: “If you have have downloaded this software pursuant to our 30-day trial and you are currently running a prior version of Capture One, a new Catalog will be created when you open v.11. This Catalog will not be compatible with prior versions of Capture 1. If you should decide not to purchase v. 11 or you want to use your prior version of C1 in the future for whatever reason, you will need to follow these steps. [Clear Explanation]
