I get error message that MODLOADER cannot be run with FORGE when trying to re-install Instant Massive Structures-IMS (It was the first mod I ever loaded after loading ModLoader.) Then, I loaded FORGE to install Castle Defense Mod. Lost IMS, and now cannot re-install IMS successfully. I was told to refresh my .jar with new FORGE download, but that didn't work.
It seems to me that the first guy responding to my earlier post today may have been correct....
Does anybody have both ModLoader and Forge installed, and is successfully using both Castle Defense Mod and IMS mod?
