[Help] IndustriaCraft2 not working in conjunction with Biomes O Plenty

I'm currently working on a private server with a custom mod pack, in it we'd like to have Biomes O Plenty and Industrial Craft 2. It seems that they are currently seemingly incompatible. If anyone knows a fix or work around any help would be greatly appreciated.
the server starts up fine but when i try to join it gives me this. http://prntscr.com/4g1eat

we are running on 1.7.10 btw

Try IC2 alone, then try Biomes O Plenty alone. Make sure you're using the latest versions. Also, it would be VERY helpful if you uploaded the fml-client-latest.log for us to see.

I use IC2-Experimental and BoP at the same time just fine on my server. O_o

sounds familiar, maybe its an outdated forge version
