Photoshop RAM Problem

I could use some help here...
As of last night, Every time I try to open my copy of Photoshop 6, I keep getting a message telling me that there is not enough RAM to initialize Photoshop, then it shuts down. This is odd, as it was working fine up till last night. When I tried to open it in safe mode, I got the message that Photoshop couldn't be opened because of a hardware or system error, and that the error is unrecoverable...However, no other program seems to be suffering from the lack of RAM problem. I currently have Windows XP Pro, with 512mb RAM, and my system is an AMD Athlon XP2200+1.8GHZ. I have tried expanding my virtual memory, to no avail. I don't know if something is eating up the ram... I have tried removing some non-essential programs, and this hasn't worked either
Hope you can help me out...

 

Don't use Photoshop myself but have you looked here for an answer?

Thanks for the advice guys...I ended up doing it the long way. A total Photoshop reinstall seems to have fixed the problem..Now I just have to track down all of the extra plugins that I had! Some of them have not copied across...Oh well, can't make an omelette...

 

I don't use PhotoShop, but I do use Acrobat and that has a "detect and repair" feature in the help menu.

Failing that, if you go into Add/Remove and select it for uninstall, it will give you the repair option.
