3.1.2 and Forestry [resolved]

[Automaton]

I'm trying to get Forestry 1.4.8.6 to work with my tekkit client (it works with my server). I've followed the directions here to the 't', but my client keeps throwing an error that I can't figure out how to fix.

Resolved the problem. Somehow I ended up with two copies of EE2 in my client mods folder. Removing the extra one cleared everything up.
