Problem opening t2dproj files after making modifications to the engine

We have made several modifications to the engine to add the functionality we need for our project; as well as some of the recommended fixes from the forums. Everything compiles fine and TGBGame works as well. However, the TorqueGameBuilder.exe that is created when we build no longer works to open t2dproj files by double-clicking on the file or dragging the file to the executable. Even after reverting all our source code changes it still has the same issue. This may mean that it was a non-source code change that we made or that we missed something when reverting. We can still run TorqueGameBuilder and open from within the app, which works fine.

I debugged through the running of the entry script when double-clicking on the project file. In CodeBlock::compileExec it tries to parse out statementList from the file, but it comes back NULL. I believe that this may be why it is failing to run properly in this situation.

We were hoping someone might have some insight as to the issue.
