Same here. I found interesting post on their forum:

"hi bro be care-full with evolution 5 script,they have lots of problems, some weeks ago i joined a new site which use this script and they have 4 main ads but when i refresh ads page its show 5,so if i click 5 ads i get suspend,
today in bittoclick i also find 2 ads for nilobux,but after i refresh its only one,so be carefull with it. "

So I was logged off and suspended exactly after I clicked those two nilobux ads, maybe you have done the same? Then it's a bug, and they hopefully will unblock us
