Compiler File Error on Build

Well, the subject line pretty much says it all. I was having an issue even getting this project to save because it was originally created in another account on the same computer. Finally got it to save and was able to work on it, but it won't let me build. I get this maddeningly non-specific error message.

Compiler error usually has to do with read/write permissions (would make sense since you've got multiple accounts going on)... check the location of where you've set your build (in preferences OR in the build/format box -whichever you're dealing with)- it may be in a folder that your account doesn't have write access privileges to... Try creating a new folder on your desktop to build to- that ought to work temporarily - the real solution is to work out the appropriate read/write permissions from an administrator level on your machine.
