Problem FML Error when attempting to disable server mods (FTB Ultimate)

[Haruchai]

The silicon termites found their way into my computer last night and apparently caused harm to Modular Power suits mod. All was well last night when I shut down the game, but today it's a 100% crash during game load. I reinstalled the mod, but that didn't help (ie, still crashes). So, ok, no biggie as I don't really need that mod. I disabled it in the FTB launcher and the game starts fine. However, as I connect to a server on my LAN i knew I would need to remove the mod from the server. I did just that (along with the config files), but I keep getting the following error when I try to connect to the server from my client:

Forge Mod Loader has found world ID mismatches. ID 1252 (ModID:WR-CBE:RedPower, type rpwireless) is missing. You cannot connect to this server.

I assumed that disabling mods was as easy as removing them from their respective folders (my google searches on the subject also support this assumption), but as you can see, that's not the case. Also, I'm not understanding why RedPower is involved, unless there's some attachment that integrates into the Powersuit.

Any ideas on how to fix?

Thanks.

modular power suits should have no effect on wireless redstone which is what is having the ID missmatch (it uses some of redpower's block placing mechanics) . What that error is saying is that your configs between the server and your client is different, no clue how that happened by removing mmmpowersuits unless you accidentally deleted wireless redstone. Easy way to fix is backup your config files first in-case this does not work and copy server's config files to yours and replace all of them.
