Until this morning Affinity Photo has worked just fine for over a year,however today, it crashes whenever I try to save a file. It seems to be so corrupted I can no longer work with it. It is also running more slowly than normal. I am running it on a Mac Pro OS 10.7.5 as I am unable to upgrade to more recent OS systems due to the age of my computer which is no longer supported by Apple.
I have already run Disc Repair, the disc is OK and I also repaired the permissions but to no avail. It still crashes. I think the problem might be solved if I trash a preferences file but there are four of them.
Question….Can I trash them all or is there one in particular I should trash ? I don't want to make the situation worse by trashing a wrong one.
Or as a secondary solution…..should I just do a reinstall which means having to go through the App Store again and that is always a pain ?
Any advise would be appreciated.
Thanks
