weird error

Did you define Wrath2D.cWFigure twice in your code?

no, that's the weird thing. I have had this project for a long time and i just reinstalled windows and everything on my computer and when i tried to work with it again i get that error. btw, it's not a managed c++ project or anything so i don't know y it would be "wrath2d.cwfigure"

how do i restore the default configurations in the project properties? i was screwing around with the settings, because i don't know what i'm doing and can't find the answer, and now there's tons of errors...

I changed a LOT of things around to see if maybe it was a compiling error and now that i have all the errors back to none, i'm still getting those weird errors, even with all my objects.

edit: well, not all of them, i have a lot more than those, but those are objects that are in headers that i need to include in more than one other header in my engine, i'm pretty sure that has somethign to do with it... anyway to get past that? also, at the beginning of every header i'm doing #ifndef __HEADERNAME__ so it only compiles once but i don't know why i'm gettin these errors.

??

is anyone familiar with this error?? and know how to fix it?
