Problem with Agrarian skies server

[Greyhair27]

When I run the agrarian skies server I receive the following.

2015-03-14 12:35:22 [SEVERE] [ForgeModLoader] Unable to launch

D:\Minecraft\ftb\AgrarianServer>pause
Press any key to continue . . .


If I press a key to continue it closes the server. I have been looking for threads about this and haven't found any but I may have missed it. Any suggestions?

Thanks

If you're not advertising your public pack here, you're doing it wrong. I know you didn't make agrarian skies because jadedcat did. So you're in the wrong place.

sorry, misread the forum category I guess
