Sigh. I've been working on my mod for a while now, I have been working day and day through on custom this custom that, and a load of detail into my personal little map I can't wait to release someday.

However, shortly after I went to compile my map earlier, I came across this horrifying error.. 





NOTE:

-> I HAVE Run Launcher.exe in ADMIN mode. 

-> I HAVE not touched any folders or files OUTSIDE my MOD folder. 

-> I HAVE been able to compile just an hour or under that before-hand with no issues. 

-> I HAVE not deleted any Sound files or anything, nor are they 'gone' 

===

I DO NOT want to re-install mod tools, as that will take FOREVER. I wish to find a quick solution. 

What does this error mean and how can I solve it? Thanks
