Minecraft Forums

I am a first time poster and a noob at modding Minecraft. I have:

• Pixelmon-1.7.10-3.3.8-universal
• Reis-Minimap-Mod-1.7.10
• OpenBlocks-Mod-1.7.10
• OpenModsLib-1.7.10-0.6
• CodeChickenCore-1.7.10-1.0.29-universal
• CodeChickenLib-1.7.10-1.1.1.110-universal (which appeared in a file called 1.7.10)

These are all within the "mods" folder and I do have Forge installed.



This is the Error Report:

P.S. Sorry if I have broken any Forum Rules, I couldn't find a full rules page.

You shouldn't be manually adding CodeChickenLib. It should automatically be downloaded if it is needed. (Or I could misinterpret and you are reading mods you have installed, of which then yes that is right, leave it alone.)

Secondary, check your Open Blocks installation. Ensure latest 1.7.10 of OpenLib and OpenBlocks itself.

Thanks for the assistance, I found the problem was occurring during the download for some reason.

I re-downloaded OpenBlocks twice and it finally worked.
