Hey guys I am having a problem. When I try to allocate more memory to minecraft to run Mocreatures I get an error. Here is the bat file path excluding the username: java -Xmx1024m -Xms1024m -jar "C:\Users\[Username]\AppData\Roaming\.minecraft\bin\minecraft.jar" And this is the error according to command prompt:

Press any key to continue . . . Yes I do have enough ram(12 GB, 10 GB free(Windows 8 uses 2 GB)), and Yes I have the latest Java and a path to it in Enviroment Variables.

For me, i only have about half a gig of allocated ram minecaft can access. The map i am trying to play, even with the default texture, crashes with the "needs more allocated memory" screen.

Mocreatures is not a texture pack. It is a large mod that introduces many new animals.

The Mo creatures problems are gone this thread may be closed there is no reason to give any answers now.
