I've had my mac freeze on me, so have had to wipe the internal HD, reformat, use DVD to set up new operating system, then also upgraded to Yosemite.
I had saved Photoshop on an external HD. With some difficulty and a few error messages I thought I had set up PS on the Mac under the new OS.
The program opens and all looks okay but when I try to open a Picture file they are all greyed out and won't open up.
Would be better to start from scratch by downloading a fresh version, and if so how do I do this?
I've been paying the monthly subscription for a year or so.
