It is quite possible that your are installing the mods incorrectly or attempting to install incompatible mods
To avoid this use a mod installer (like MCPatcher) and install Forge Mod Loader first so all your mods work together
They don't.
i think you need to downlode mod downloder (if thats what its called)
Because 1.6 hasn't come out yet.
You have to download the TooManyItems Mod for Minecraft. Search it up on the forums and download the ones that correspond with your minecraft version. When you update minecraft your Mods wont work because they will become and old version so wait for the mod maker to release a new version of the mod that works with the new version.
there is a glitch right now that wont allow you to read the users agreement. give it time and they will have it figured out.
actually you have to buy the mods once you buy the one you wont its free.
Re instull Minecraft
problems? contact mods or admins
well minecraft 1.3 comes out some time today and 1.4 probably wont come out for several months and to update you just log in to the launcher and download the update.
you wont believe what it is its 12345
perhaps one of the mods is corrupted by the mod maker take it out on them ask them
it might be your visa card try email visa and/or minecraft for suport.
