Hi there,
I'm a fairly new affinity user and so far am really enjoying replacing adobe with it. However, today I found my Designer file, after switching to Photo to do some brush work, could no longer be opened.
I get a warning message saying the file is corrupted when I open it again in designer. It still opens fine in Photo. I'd saved the file message under a different name and get the same result. I've also changed the file suffix to designer but that didnt work either.
I'm using a 2012 rMBP with 10.10.3
Also the Photo beta is 1.1.2.24216
Cheers,
Daniel
