Joining Server Problems. HELP!

[x3x33]

Im sorry if im posting this in the wrong place. I literally just created this account so im new to this forum.

I have recently started playing on my friends Tekkit server. I have been able to connect and just play for the past 3 days. But when I launched the Technic Launcher, it offered an update. So when I updated my Tecknic and then attempted to connect to the tekkit server, I am getting a message saying,

The server requires you to have the following mods:

mod_IC2 c1.95

mod_IC2NulearControl v1.1.6

mod_BuildCraftTransport 2.2.14

mod_AdditionalPipes 2.1.3 (Minecraft 1.2.5, Buildcraft 2.2.14, Forge 3.0.1.75)

mod_BuildcraftCore 2.2.14

mod_CompactSolars2.2

mod_Railcraft 5.2.4

mod_RedPowerWiring 2.0pr5b2

mod_RedPowerCore 2.0pr5b2

mod_RedPowerLogic 2.0pr5b2

mod_RedPowerWorld 2.0pr5b2

mod_ComputerCraft 1.33

mod_IronChest 3.3

mod_NetherOres 1.2.5R1.2.2

I dont know how to get those mods or even insert them. If someone could assist me that would be greatly appreciated. Thank you!

You're using the dev. build. Wipe your tekkit folder and use the recommended build. I can't even see the picture and I can tell that's what happened. :)

How do I wipe the Tekkit Folder?

Delete %AppData%\Roaming\.techniclauncher\tekkit, run the launcher and make sure you're using the Recommended Build (3.0.3 for Tekkit), login and wait for it to re-download. Update all your settings.
