X-Code: "The stack backtrace has been logged to the console."

[DonFuzzy]

Hi, I've been using Xcode to write CoreAudio code recently, and it worked fine. Then one day, I get a message saying...

Uncaught Exception: ***-[NSCF String replaceCharacters inRange: with string:]:nil arguement

The stack backtrace has been logged to the console.

Then whenever I tried to open a xcodeproj. file I get a similar error, that includes "The stack backtrace has been logged to the console." Then, Xcode won't let me open and compile my xcodeprojects, or my cpp files.

I tried reinstalling Xcode twice and I still got the same errors. Does anyone know how to fix these problems? If so, I'd greatly appreciate it if you could respond asap.

When you reinstalled did you uninstall properly first using the scripts? If not, I suggest you so.

The uninstall scripts.

I entered $ sudo /Developer/Library/uninstall-devtools --mode=all into my terminal. Then I restarted my MacBook, and reinstalled X-Code 3.1. Then I tried opening XCode again, and I got the same error as before. I tried running a TremoloUnit AU plugin available as an X-Code project file on Apple's Core Audio programming website, and X-Code wouldn't let me open it.
