Everytime I open my run.bat file it displays this error,

I saw somewhere that you need java 8 so I got java 8, thats not the problem. I also ran forgeserver.jar is command prompt and I got this error

 

"C:\Users\...> java -version

java version "1.8.0_301"

Java(TM) SE Runtime Environment (build 1.8.0_301-b09)

Java HotSpot(TM) 64-Bit Server VM (build 25.301-b09, mixed mode)

 

C:\Users\...>java -Xmx4096M -Xms4096M -jar forgeserver.jar nogui

Error: Unable to access jarfile forgeserver.jar".

 

Another fix I've tried is running my minecraft_server.jar instead, It works but does not load all the mods correctly.

Please help I've been working on this for several days, it would mean a lot.
