Can't save in PS7 and can't open Imageready

I've been using PS7 for the past year now with no problems up until a week ago. I"m running it on XP and well when I go to: Save As... and click to save the image as .png or any other format it won't save. I get no errors or anything. The only format I can save it in now is .pdf. This is now a problem seeing how I run a few websites and can't save my graphics in the correct format. Also another problem is when I click "Save for web". The menu and everything never pops up like it used to. When I click it, it doesn't do anything but hide the dropdown menu. I've tried the shortcut keys and still have a problem. I get no error messages or anything. Is there a solution to fix this problem?

Alright now with Imageready 7, I used this to finalize my graphics but no I get an error when it says "Loading Plugins..." I get the message "There was not enough memory to complete opening of Adobe Imageready 7". Funny thing is that it always worked before and never had an error. I know this computer has enough memory to run it. This problem isn't as a big concern as PS7. But is their any solutions to these problems? If you have a solution to this feel free to e-mail me at Thank you!
