I will look at the account registering problems tonight if I can and report back.
As far as event booking goes the plugin seems pretty good. Any issues we've had have been fixed pretty. It's pretty powerful, the only catches are it treats sessions like separate events. And there's pros and cons to group booking. But it spits out a spreadsheet and emails admin and the registrant as well as other nice things.
It's worth the money for the bfta I think.
It would be great to have a tailor made version that handles booking, scores and results just how the bfta would like, but considering its price it's pretty good.
