[Server Forge mod loader error]

Just recently got my friends into playing tekkit classic, so I tried making a server, but even though I gave it enough ram, it now seems that it still won't work.

Below is the direct copy paste of the CMD

C:\Users\***\Desktop\New folder (2)>java -Xmx3G -Xms2G -jar Tekkit.jar nogui
