DAMN!I had the same error and I spend like two weeks figuring out what was the problem!!
Ok here it is, the solution:
Whenever you create a developer license, make sure to keep it up to date, like recreate it every 3 month or so. Because, when it gets outdated, your TV applications simply STOP RUNNING, no matter if there are any application licenses included or not!
It throws an exception like
"Attempted to read or write protected memory. This is often an indication that other memory is corrupt."
most likely on TVEngine.Init3d.
Ok folks, I really love TV and escpecially the support, but here is one complaint, remember I spend two weeks on this, and it would have been so easy!
WHY can't you give a warning like "Your license file is outdated!"

?
