I'v never used branching till yesterday so I didn't knew that I should make the branch our of the trunk. So I branched a subfolder and this caused some side effects like accidental switching the trunk to branch ... this resulted in overwriting the trunk with the subfolder and deleting everything else inside the trunk = destroying my working copy ;/
Now I'm in the situation that I want to override this problematic branch with my working copy. How can this be performed? I'm using Tortoise SVN.
