Error loading photoshopimport.aip plugin in Illustrator CS4
Hello, I'm currently using Illustrator CS4 and just updated my Mac to OS X Yosemite. After installing the new software, I've got some bugs with Illustrator. Namely, upon opening the program, I get the message "Error loading plugins". The plugin in question is "photoshopimport.aip". I'm not sure if this is related to the next issue - I'm no longer able to open .tif files in Illustrator and says that they are "an unknown format and cannot be opened". I have uninstalled and re-installed all Adobe programs, but I still get the same error messages.
Naturally, most of the work I do is in Illustrator with .tif files. Can anyone offer some help with these problems? Is this a case of the new OS X and CS4 having compatibility issues? Am I going to have to bite the bullet and upgrade to a newer version of Adobe? Any help you can provide would be greatly appreciated.
