Bizagi Modeler v4.0.0014 won't open process

I update Bizagi Modeler from the 3.9 to the 4.0 and it won't start as usual.

I was using it without problem till now.

After clicking on X (because of loading) I also get this message:

,,Error loading Model:

Timeout error ocurred loading the page.,,

After clicking on OK, Bizagi Modeler just quit.

Could you please give me any advice!
