I just read a topic with the same problem and someone said to delete ModLoader.txt on client+server but that hasn't worked.
So far I have tried it with a completely clean client + server, I deleted all the files for Tekkit and ran a new server.
When I join I get a message telling me:

Yet on my server console I am seeing a message that says:

I know it's pretty pointless posting all of it but I know it is telling me I am joining with the correct mods (I haven't read the list word for word but nothing seems to be missing...)
The versions numbers should be right, I auto updated my client with the launcher, and the server I downloaded the new one and put it in a new folder with a new map to test (2.1.1 right?)
Nothing has changed in my computer dependency-wise (Java version is the same, I haven't changed OS (Win7) and I haven't edited anything) since it last worked (2.0)
So all this points to 2.1.1 being incompatible in some way, I don't know if anyone else has this problem but I'd really like to start playing Tekkit again (Vanilla is getting boring again which I only switched to because of all the updates from Mojang)
Btw I really hope my code is wrapped when I post because it's not in preview mode!
If not I'll add a newline at appropriate places
> It didn't wrap, added newlines :)
