I can't even use Rush skill

Hey, there's a problem with my rush skill. I can't even use Rush skill even with my buttons and double clicking. Nothing works. I tried to reset and put it again in my key settings. Still I pressed it again and nothing works. Does anyone know how to fix this problem?

Two things come to mind:
1.) You're not using the correct weapon. For example, Paladins can only Rush with BWs and Swords.
2.) Glitched skill usage. Just leave the map and come back and it should work fine. I had MW that didn't work for some reason one time xD And I have no idea what causes this...

As Kajiti said. If you're using the correct weapon, idk what to tell you...

I used the correct weapon but anyway. Close this topic now. I got it fixed already by rebooting my computer.
