Weird Forestry server error

[Venom]

Got the client and server both to run forestry(version 1.4.8.6) as well as smart moving on 3.1.1. However whenever a player crafts a carpenter the client crashes with this error

Any ideas? Maybe the wrong version of forestry?

Actually i fixed it. I must have had an old config file left over from a rebuild. I deleted the config and it worked.

Does the forestry file work right when you put it in? In other words, please could you give a explanation of how to do this. I'm great with ssp modding, but server modding is extremely foreign to me.
