Forge hangs at "opening main window"

[Jessica]

Hi

My latest Forge version was working great and suddenly one day it hangs at "opening main window" (no matter how long I wait).

I reinstalled Forge completely, and even my Java. I'm on Windows 10 64 bit.

Anybody can tell me what to do or what to try? I can't get past the "opening main window" screen

Problem solved: I deleted the userDir and everything works again !

I'm having a similar problem.

When starting the game, i get this error message:

How did you fixed yours? What do you mean by deleting "userdir"?

Read manual.txt in forge's installation directory. You can find the location of that directory there
