Ok, so I have installed forge, and installed 2 mods : Fossils and archeology / Rideable Spiders. But whenever I try to install a third Mod, no metter what mod, the game crashes before the menu screen pops up. HELP!!!!!!!!!!

Are you using 1.7.2 or 1.7.10? Rideable Spiders does not seem to be compatible with 1.7.10.

Im using 1.7.2 but thats not the issue.....the 2 mods are compatible and work fine. i just cant seem to add a third mod and run the game successfully

Well then we can't help without a crash log. Post a crash log and then we can help.

here it is.....

Change Entity ID 3 from Dragon Riders or Rideable Spiders in the config files. Use the ID list (search for Data Values on Minecraft Wiki) to help you. If you plan on adding a lot of mods, I suggest you make yourself a chart using Excel.

Ok...whatever you just said, i will try to make sense of it and give it a go :3
