I decided to give it a go despite the fact that if you set the reviews to "recent" you'll see nothing but a see of don't recommends.
There is some securtiy program attached to the game whereby it'll close it down if it detects a "suspicious program". I've tried multiple times to get this running by closing down things that I would rather have running but I wouldn't determine as being essential (including not having steam open which works for some), however, this was to no avail.
From my googling it seems that maybe if you uninstall your antivirus then that may be the solution, but to me that 100% unacceptable.
Whilst I get that people that bot or hack are incredibly annoying (and I'd hope this program sucessfully filters them out or it's entirely pointless to have) if you're going to implement a security system then it really should be designed to be far more accurate and not some sort of blanket, is there anything at all running on your computer, well no, you can't play - which is what it appears.
So yeah, whilst I'm sure some people will get this working, I presume depending on the anti-virus you use (or if you use one at all) and other factors, I really wouldn't waste any bandwidth on it, which is a shame because I've enjoyed similar games like dragon nest (and and never had a problem with any of them despite having played most of them around).
