Hi, I have the same issue with "Could not complete your request because of a program error" and it happens when I try to "Save As" to PDF's and EPS's files. I have more than 100 Gb free and 2 Gb on RAM, I use Photoshop CS4 on MAC and I don't have ANY issues ralationed with corupted o duplicated fonts. I'll check in internet more possibles solutions for this because all of this solutions don't work in my case. If someone could help me. I'll be grateful.
"Could not complete your request because of a program error" was the message I received when trying to save a particular .jpg file in CS4 using Mac OS X 10.6.4. (I had seen the same message before upgrading from 10.5.8.) Other, similar files - size, extension - did not have the problem. I reopened the problem file using Preview and saved, and that solved the problem in Photoshop. I recognize this fix may have limited applicability - hope it may help someone.
I am having the same situation today, after working on psd and eps files in Photoshop yesterday, I'm getting the error message about Program Error. Nothing with a jpg, just psd files I created with letters (so it's art) I copied and pasted from old broadsides, so there's really no fonts involved. I did however have some other font issues with my computer this morning--how can that be related? My Mac system is 10.4, but I have plenty of RAM, and had no problems yesterday. Now Photoshop gives that message before I even do one or two things to the file! Any ideas o how to fix this? thx
