Need help with a crash

[Robert Russell]

Trying to launch a new mod pack I put together for me and my friend to play. I have all the mods in my pack updated to the newest version for 1.7.10 and the forge version I am using is 10.13.4.1558 (the recommended download). Here is the log.

You installed a coremod (Inventory Tweaks) built for 1.8+, but you're running 1.7.10.

Ah yes, thanks.
