I appreciate this is a somewhat old thread, But I was just wondering if upping your limit solved your problem betfair winner?
I've been having the same problem for a few weeks now, but my liabilities are nowhere close to my exposure limit and my funds are fine covering all my active bets by a substantial margin. I have deselected the option to Limit one bets maximum liability on the betting options settings page of mfp, but the problem still happens.
Anybody else seeing these sorts of errors when they check their program logs?
