Problem with ACEonline Launcher, please help!

Im playing a private server on my laptop which running Window 8. Every time I try to open the game client, enter user name and pw. After hitting start button, the client disappear, the game wont start, nothing happens. I thought the problem may come from hshield or the new window, cuz I was playing it just fine with my previous laptop which running window 7. Btw, my lapop is Lenovo Y580 , a gaming laptop, it should be able to run these kind of games.

Please help
Thank alot

The most P-Server are not Win8 compatible!!!! use Win7 is better for Gamers!

i only heared bad things from win8 thats why i wont use it (for now)

Ace Online or AirRivals is Win8 kompatible but no p-server except NextGenAce, because its ep 4.2
