1. [exsample on my pc were it was found.] C:\Users\PatEvans\AppData\Roaming\.minecraft\config
2. open this in notpad.exe > IC2.cfg
3. edit this blockDynamite=236
blockDynamiteRemote=238
blockElectric=227
blockFenceIron=232
blockFoam=222
blockGenerator=246
blockHarz=240
blockITNT=239
blockIronScaffold=235
in that file to thoughs numbers above.
4. close ur terkit client and hit save on the file menu on this IC2.cfg file
and reopen ur terkit client if all gose well it should load up like
mine did.
5. I hope this helps out Cuz I had the same error but it was expected 238 and got 235
for some odd reason :S ?
