Thanks Quadraxas.

I found an error code, looked it up in the manual and did a search but there seems to be no solution to my problem.

Here is the error code:

Error E1513: Crash in def_startup
Crash in def_startup - any key to abort
Program aborted

The thing is, it even gives this error on a wed with no script file. Like a new project with nothing but a hollow cube.

It is a code error but i have written no code.

Thanks for any help.
