I have several PS action files (.atn) that originally works on PS CS2. However I copied them to an external drive as I need to reformat my pc. I then placed them back to the pc and run them using another copy of PS CS2 from a different cd as the previous cd is spoilt. However, I received an error messages while trying to load any of them, "Could not load actions because the file is not compatible with this version of Photoshop." Tried to load them on PS CS3 as well but also encounter the same error messages. Note that they are loaded in the correct path. The same action files that I can obtained again from it's original source can be loaded. Unfortunately some of the action files that I have is self-created and not obtained elsewhere. I suspect that these action files are corrupted when I copy and moved them back and forth. How do I solve this problem? Thanks for any help rendered.
