Had a weird error come up after I un-zipped the folder for v0.9.2 (before c or d versions came out) where the folder seemingly duplicated itself so I had two of them. Strangely deleting one left the other but it was completely empty. So I just had an empty folder on my computer say it cannot delete itself as it "Could not find the file".
The newer versions haven't had this issue but still want to let ya know about it. I fixed it by using CMD to remove it, so at least its gone now :D
