Well I got interesting news.
1. I managed to load all of the mods, and the app will start without any bugs. Which is great!
2. I managed to start a singleplayer game, which works... Somewhat (see below)
3. When I attempted to connect to UDICraft, everything looked tip top until I got this message that you can see in the attachment. I could have simply try to find that mod and drag it out of my mods but as of now I have another concern.
When I attempted my singleplayer game, I managed to log in and all. Unfortunately, I guess my computer is unable to handle all the massive data that it has to provide, I could move and function well for the first 2 or 3 minutes but after that I've had lag so intense that I couldn't even chop down a tree.
Is there anything else I could do to try to fix this? I saw that my minecraft only allow the usage of 500mb of ram, if I could up that to 2gig, perhaps it would help out, or maybe you have other performance suggestion for me?
