Hello, I've been trying to add the IC2 64x patch to the .zip of the texture pack. I followed the instructions, but I can't copy-paste the files from the Patch into the texture pack's .zip. Paste is grayed out. Is there something I'm doing wrong?
Use Winrar, if you aren't already.
That should solve your problem.
I have the same issue, and I'm using a mac... so I don't exactly have the access to Winrar or a version of RAR that i know how to use to unzip and paste the patches.
