Whats wrong with kickstarters payment system? I find it easy to use and like it alot I just have to pledge and everything is automatic (more or less) ^^ (Not automatic the first time ofc)
As for the lack of update: I didn't really want to post another non-update as there wasn't a huge amount to say other than "we have had some very very minor issues and Kickstarter isn't quite ready - we will be back with you very soon".
I did post this little picture in the pre-update discussion thread though.
Edit: Have something else
