Guys,
I had an old secret link account, and after site's transition to email-login system, I cant access my balance!
I've been doing correspondence with Randian Hero from support for more then 2 months!
He only replied about login issues, but looks like doesnt wanna hear about the money

Has anyone else also lost money that way? w/o even making a bet

No, all worked well for me. My balance transferred seamlessly into my account. Bettwe this way - at least it stops people from sharing their secret URL on here.
I hope you manage to get your funds released...
