Problem New Private Direwolf20 Server - Incompatible Heap Sizes

[AerionM]

Hello!

I've been trying to set up a server for one and myself using the Direwolf20 mod pack, and I've been running into issues all day, and can't seem to find any solutions that work for me.

The most recent issue is that the ServerStart.bat gives this log in the Command Prompt when I run it(this is the default batch file, un-edited):

Spoiler

C:\Users\user\Desktop\direwolf20_17-server>if NOT EXIST minecraft_server.1.7.10.jar <
echo "running install script!"
call FTBInstall.bat

"make sure to read eula.txt before playing!"

C:\Users\user\Desktop\direwolf20_17-server>java -server -Xms2048m -Xmx3072m -XXermSize=256m -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -jar FTBServer-1.7.10-1272.jar nogui
Picked up _JAVA_OPTIONS: -Xmx512M
Error occurred during initialization of VM
Imcompatible minimum and maximum heap sizes specified

C:\Users\user\Desktop\direwolf20_17-server>pause

I've tried changing the values, and it continually says this.

I'm running Windows 7 64 bit, 16GB of RAM, no additional mods.

Any help would be greatly appreciated!
