Forge 1.7.10 crash entering world (No Mods Only Forge)

[Ezio_Wolf]

My friend and I have been trying to join this server for the past 2 days and I was able to access the server without forge or any mods at all. I was also able to access the server with Forge 1.8. The trouble is that the tekkit world the server has is at 1.7.10 and every time i try to load the server my minecraft crashes.

 

Keep in mind that I do not have any mods installed other than Forge. Forge is the only mod that i have on my computer and it crashes. My Java is up to date, and my minecraft runs fine if I just switch my profile settings back to "Latest Version". Me and my friend have given up on what to do and cant find any tutorial videos on youtube for my specific problem.

 

PLEASE HELP!
