I downloaded some trial plugins and then removed them and ever since, CS5 is not working well. Sometimes when I open it and go to file open to open an image, everything is grayed out and I have to close down and re-launch. When I open an image and want to look at the file info, everything freezes and I have to use task manager to close down photoshop. As well, my bridge is not working correctly. I want to uninstall and then reinstall, but I thought that somewhere that I read there are specific ways to do that or else the program thinks you're trying to load it on another computer..? Thanks for any help and dircetions/instructions that you can give me.
For Uninstalling, and then Reinstalling PS CS _, I would go to Help>Activation and Deactivate, then go to Control Panel>Add/Remove Programs (on a PC, but bound to be similar on a Mac?), and choose PS CS _. [The reason for the underscore, _, is that this should work with all versions, at least since CS.]
When that completes, download and run the Adobe Creative Suite Cleaner Tool a few times, rebooting between each session.
Then, Reinstall PS.
As a test, and perhaps an alternative to Uninstallin and Reinstalling PS CS 5, if you are on a PC, check to see if you have a System Restore Point, prior to the installation of those trials. If you do, then first - create a new System Restore Point for today, and then boot to Safe Mode. There, you should be presented with the option to Restore the System. Navigate to that System Restore Point, prior to the trails, and choose it. The system will then ask to be rebooted, after a few moments. Do so, and then test PS. Does that fix things?
On a Mac, I think that the equivilent of System Restore is something like Time Machine, but do not know if that is part of the Mac OS, or an add-on product.
