I recently got a new computer. Problem is, Adobe claims my serial number is invalid (despite the fact I bought my photoshop from them) so I can't transfer it to my new PC. Turns out hackers found the number via a keygen so now its likely blacklisted. I'm trying to deal with it but doesn't look good. In the mean time I intend to play around with blender and maybe find an alternative program. Hopefully I can get back into it soon.
UPDATE: I got it to work so we're back in business, though I did try GIMP and I may try that out from time to time too
