ID Mismatch!

[Nickpipitone]

This is killing me. I used FTB but then my server players got bored of the same mods so I used a custom modpack on Tekkit. The problem is that every time I try putting GregTech on my server and client, it crashes saying ID Mismatch (https://dl.dropboxusercontent.com/u/138461102/Untitled.png). I have spent HOURS trying to fix it. Going one by one making sure ALL of the IDs for GregTech match after Copy/Pasting the config in there. It used to work but I added a bunch of mods and now when I take them out it still doesn't work. Please help me my server users are getting irritated!

 

(OH btw Redpower crashes with GregTech after I added those mods too, but it used to be compatible before. Even when re-installing the whole thing somehow it just doesn't wanna work. After choosing GregTech is better than redpower, it decides to screw up the IDs.)
