Problem Can't start my server using a batch file

[IamVictorious]

Hello, I'm trying to add more ram to my server, and I know how to, but whenever I try to start the serverstart.bat, it opens for a split second, then dissappears. when I add pause to the code, it tells me java isn´t recognised as an internal or external command, program or batchfile. I've tried re-downloading the server file, that doesn't work. The code I currently have in my serverstart.bat:
java -Xms512M -Xmx1G -jar ftbserver.jar
pause
please help,
many thanks in advance!

Does the server have 64bit version of java? You need the 64bit version to allocate more than 1GB to java.
Follow the directions about java in the link provided below. Get only the latest 64bit version and make sure you uninstall all other versions.

If you have the 64bit version then please provide the error logs pasted to pastebin and linked here. Instructions below.

Ok, I've run into another problem just now: when I start the server using the ServerStart.bat , I get this error:
[WARNING] **** FAILED TO BIND TO PORT!
[WARNING] The exception was: java.net.BindException: Address already in use: JVM_Bind
[WARNING] Perhaps a server is already running on that port?
I've looked it up on google but couldn't find a fix that worked for me (I tried removing java.exe in processes, I redownloaded the server folder). When I use the normal ftbserver.jar launcher it works fine, but with the batch file it doesn't.
would really appreciate some more help, thanks!

**** FAILED TO BIND TO PORT!
The exeption was: java.net.BindExeption: Address already in use :JVM_Bind
Perhaps a server is already running on that port?
