Can't start Forge, help?

[MadBrains]

Hi there, been having problems for the entire time while trying to set up a server. I don't know why this is happening and need any kind of help with this. I've been Googling for the past 3 hours and to no avail ): . So any help would be great!

 

Thank you in advanced!

Use Java 8 instead of Java 9.

 

Also, 1.7.10 and older are no longer supported on this forum. You should update.
