When using IE8 and I try to purchase credits, the Paypal page does not load when I click submit. It works in FF and Chrome, but not in IE8. Upgrading to IE9 now and will test again.
Update: works in IE9, seems to be a bug with IE8 only.
I apologize for the delay in getting back to you on your issue. Tonight I've released a very-long-overdue update to vBCredits which contains dozens of bug fixes and improvements.
Can you please upgrade to the new v2.1.0 and let me know if your issue still persists? We can work from there now that all of the patches etc are up to date. Thanks! http://www.dragonbyte-tech.com/f77/vbcredits-ii-deluxe-v2-1-0-released-9187/
