Photoshop Cs2 Help

Alright well I was wokring in photoshop with the paint bucket tool and I was clicking (on the image I thought) and all the sudden the background behind the 400 x 150 size sig I was doing turned into the color I had my paint bucket tool selected as. I tried to just make it the same color as it was before with the paint bucket tool but it didnt work. I cant figure out how to change it and its irritating me. I tried to see if their was a feature where I can have all the default settings restored but I didnt find anything. Maybe Im blind?

Anyways if anyone knows how to fix this please let me know. Your help is greatly appreciated. Hopefully I dont have to reinstall CS2 completely because I cant find my disc...

Here what it looks like..

First person to sucessfully get me to fix the problem will get 60 credits.

 

You can try goin to:
Window<Workspace
Default Workspace
dunno if it will work exactly..

 

Can't you undo, or press ctrl + alt + Z? to get back to where you were?

or you could close the picture without saving it and reopen it...

 

make sure the layer that u r tryin to color is selected

 

push f until it returns to normal

oh and if ur using photoshop for web graphics, use RGB, not CMYK

 

take off quick mask?
