E-Prime 2 is suddenly unable to load from file

[Larmoyanz]

Hey everyone! 

I've got an experiment which worked perfectly fine yesterday. 

Today however it doesn't. 

Everytime when a list should be loading the following error occurs: "unable to load from file". 

I didn't change anything, so right now i'm completely clueless. 

Does anyone has an idea how to fix this? 

Thank you!
