Ntw loading problem

Hello i downloaded ntw and it was working fine.i stopped playing the game for a month. then i wanted to play it again so my brother rebooted the copmuter and i downloaded it...when i clicked play it went to the loading screen..and it just stays there..thats my problem..if u know how to fix this plzz help...thankyou. also i tried reinstalling it twice

After a month it can be:
The case needing to be cleaned out,
Need to delete all mods, delete the scripts folder, and verify your game cache,
Update Windows Update manually and install software options,
Update your graphics drivers.

Or it May just be the problem in this threads:
