So, here is my problem, I'm currently running a server of my own that has Tekkit's newest version installed which uses 1.5.2. This Tekkit requires use of FML version 1.5.2. I managed to get the new launcher working with FML 1.5.2 and loaded the game up, but when I try to actually get in my server, FML gives me the list of mods I need to play on the server. So seeing this I got to start installing the mods. First one up is computercraft, of course I'm not retarded, I download the right version for 1.5.2 which would be ComputerCraft 1.53. I take it like normal and place it in the mods folder. When I do this though, Minecraft crashes upon trying to load the menu. As soon as I take the mod out of the folder, 1.5.2 with FML loads up just fine. All I'm asking is what I need to do in order to get these mods installed and working through version 1.5.2. I know I'm not using the latest build of FML, but you can't really use Tekkit with FML 1.6.2 when the newest Tekkit runs on Minecraft 1.5.2. This new launcher is really pissing me off. Can't attach the log, says it can't access file upload path.
