I try to remove folders from root directory and redownload Direwolf pack (DW20 1.6.4 1.0.14), but problem is still here. Can anyone help me? Thank you very much.

Looks like something's conflicting with Railcraft. That's as much as I know.

Or, can someone send me config for Thermal Expansion, microblocks and for Railcraft? Thanks.
