I've been having trouble with Bet105 for a few weeks now when betting player props. It actually seems much better now since the upgraded site.
FYI, they've also dramatically reduced the number of offerings in different/smaller markets. The decision was made by their risk management team (as explained to me by customer service).
For example, on a typical MLB game they previously were offering around 800 bets. Now, it's well under 200. You can still make the common types of bets...these were for smaller markets.
