Problem with building

[parveln]

Hello, when I am trying to press build or build and run code blocks opens a new project called istream and it has about 20-30 errors. This started to happen after I pressed build and run on a project which had already been built. Now I cannot even build the simpliest programs and nothing works. I have windows 7 btw.

Seem to me you have "corrupted" istream header.
this should end with #endif and not #end.
