To get you rank back (if its reseted) just follow these easy steps:
1- Once you noticed your rank is reseted, do NOT play a game as it may save over your old progress
2- Close the window without login out from ARMOR games
3- Reopen Armorgames directly on Phage wars game, for example, put phage-wars-live... the open it
4- Login in Phage wars if you need to.
There you go, your rank is back ;)
Try it :D and if its to late.. next time now you'll know what to do n.n
