Hi, all was fine until a few hours ago i stupidly pressed the update tekkit button in the popup. since then i havent been able to acces my multiplayer server. it keeps saying that i dont have the required mods. Can someone please help. i am running launcher build 1.0.1.3 and modpack version 3.1.2| 1.2.5 ( the latest and recommended build) i know this is the right build as everyone else is able to connect using that build. the list of mods that it is asking me for is: mod_Railcraft 5.2.4 mod_EE 1.4.5.1 mod_CraftingTableIII (Beta1.8, MC1.2.5) mod_CompactSolars 2.2 mod_IronChest 3.3 mod_IC2 v1.95 mod_ImmibisCore 48.2.1 mod_IC2NuclearControl v1.1.6 mod_TubeStuff 48.2.1 my current versions of the mods (listed in the mod tab on the minecraft menu) are: mod_Railcraft 5.3.3 mod_EE 1.4.6.5 mod_CompactSolars 2.3.2 mod_IronChest 3.8 mod_IC2 v1.97 mod_ImmibisCore 49.1.1 mod_IC2NuclearControl v1.1.10 mod_TubeStuff 49.1.2 how would i revert these mods back to the versions that allow me to play on the server? Thank you
