I have been having the same issue.

 

[Chaka]

Can we get a Paste ( paste.feed-the-beast.com ) of the full log?

 

[Nightwolf009]

uploading the server and ForgeMod Logs.

 

[Wagon153]

Uninstall Java 8. Install Java 7 64 bit.

 

[Nightwolf009]

Will try when I get home, thanks Wagon

 

[Nightwolf009]

Now up and running, thank you Wagon
