ETA: It seems that I had two versions of Valentina on my computer. I'd assumed that the old version would have been uninstalled. I uninstalled it manually now and that fixed things, but could you have the installer uninstall old versions automatically?
Original text: I just switched to the latest version a few days ago. I worked on a file that I'd created before, saving it several times. Today it alerted me that if I saved the file now, I'd lose backwards compability with older versions. I saved it anyway (wasn't planning to downgrade to previous versions!). Right after that, when I tried to open it again, I got the following error message:
Exception: Invalid Version. Maximum supported version is 0.2.4"
How do I get my file back?? Help!
