Server Won't Come Online/ Can't Connect

Alright, so basically my server is a Direwolf 20 1.7.10 Version 1.03 (FTB). I came on to play today after almost a month of not playing, and it was working well. Then all of the sudden it said Server Closed. I could not restart it so I went to support and they said to delete server logs. I did so and it restarted, but then I got into the game and it had me floating in a void for 5 minutes before it said Server Closed again. Then I decided to delete everything and reinstall, following everything the post about installing 1.7.10 FTB said. Now it wont even come online and a constant console message comes and it goes like:
