Server won't work

[ikkyblob]

Title: Server won't work

Version: 3.0.3/3.0.4

OS: Windows 7 home premium 64-bit

Java Version: The most recent java 7 (build 5 I believe) 64-bit. According to my command prompt: java version "1.7.0_05" Java SE Runtime Environment (build 1.7.0_05-b05) Java HotSpot 64-Bit Server VM (build 23.1-b03, mixed mode)

Description of Problem:

All I know is that it doesn't work and it starts upon the loading of mods. I think I may have received a similar error before, but I cannot remember what I did to resolve it. I have deleted all my java versions and downloaded and installed the most recent java, but it still won't work. I've also attempted to get it working by lowering the heap size (or whatever its called), but to no avail. I have also checked around the forums, but I haven't found anything helpful.

At this point, I would probably grab a new copy of the server software. Save your world.

Thanks, I think I just had to clear out the mods folder and such
