Crashes and Freezes with a tekkit server.

[crazegewd]

I'm running a server for me and two friends, however my computer freezes regularly when I have the server running. This only happens when I'm running the server, and never during any other kind of computer activity. I have to use a modified start-up file as the one provided doesn't work, the command prompt tells me that "java" is not a recognized command. The command I use is as follows:

@ECHO OFF

IF /I "%PROCESSOR_ARCHITECTURE:~-2%"=="64" "%ProgramFiles(x86)%\Java\jre7\bin\java.exe" -Xincgc -Xmx1024M -jar "Tekkit.jar"

IF /I "%PROCESSOR_ARCHITECTURE:~-2%"=="86" java -Xincgc -Xmx1024M -jar "Tekkit.jar"

PAUSE

In my Program Files (x86), in the java folder, I have jr6, jr7, and jdk1.6.0_22, I'm not terribly sure if that is important, but java seems to be the leading issue here.

I'm also running the server through the latest LogMeIn Hamachi.

Please help, this is the only way all of my friends ever get together in any form.
