Error E355: Startup failure

My game was working fine until just a few changes I just made.

It game me this error:
Error in Line 5729
Syntax Error .. 6.285 sec
Error Compiling Level_001.C
Error 355: Startup failure - any key to abort

The problem is that my main script only has 5728 lines. Also it usually tells me if it's crashing in a different script. How can I track this down?

I was refactoring my code. I think I probably just hit a key somewhere by accident...

Ah ... got it! I missed a parenthesis in one of my scripts. Odd that it did not mention which one!
