Error code 62

Maybe you have missed something. Credits can not be added to your account without payment. Only after you complete payment account with credits is created and e-mail with username and password is sent to you.

Very sorry, this was my fault.
My browser configuration was leaving out some pages, and the Paypal page was not visible. I've fixed it, and have ordered my 7 credits.

However, entering my username and password supplied in the email, and attempting to unlock, I see the following:

Unlocking, please wait ...
Error connecting to server !
Error code 62
unlock failed !

Please write username that you received after credits purchase, then we would be able to check more.

Also, it may that device which you try to unlock is overtaking your connection.

That was it! I had overlooked the device was in a higher priority order than my regular network connection.
I have sucessfully unlocked it, added my new card's APN, and it works fine.
Sorry for being a pain, I couldn't wrap my head arount what was going wrong.
Thank you for everyone's help.
