[Minecraft] FTB error

[CorruptDictator]

When I try to join I get the following.

Forge Mod Loader could not connect to this server
The mods and versions listed below could not be found
They are required to play on this server

AdvancedMachines : 4.7b
GregTech_Addon: MC146_V2.77f
TC: 3.1.13_030
drceph.petrogen: 1.2.1
AdvancedSolarPanel: 3.3.2

I just installed FTB today and when I start up it says 60 mods loaded and active.

Hello,

Did you choose the MindCrack mod pack from the MODPACKS tab? I haven't seen that error yet.

I didn't choose anything ,just downloaded and launched.

Yeah you have to select which modpack you're using... In tekkit there were several in the launcher, our server happens to not be the default modpack, and has a few more mods to play with.
