I’ve been trying to sign up for Click2Pay for two days now, and I keep getting a 501 error. I tried to sign up with both IE and Firefox, I turned off my popup blockers, and I tried using a different computer too. No success. 
I called the support desk, and they said that their server might be overloaded and that I should try again later….
I signed up for Moneybookers instead — that went smoothly. Here is a referral link if anyone would like to sign up under me. :bigsmile:
