For those having problems on making vjoy and joy2key work on windows 8:
1.Manually add vjoy and joy2key to your firewall's allowable programs list. (PS. joy2key is not readily available on the "Allow another app..." checklist, you need to browse the path of the application)
OR you may turn the firewall off xD,
2.Run as Administrator (Also on eCollidex hack)
3.Profit
