Hey pinkhorse,
Welcome to the eForum, this is a great little community and I am in no doubt you will soon be helping everyone else out.
It sounds like this is due to there being to little credit on your account, you say you have topped up, I want to double check this has gone through correctly.
I have sent you an email, please can you reply and we will be in touch as soon as we can.
Many thanks,
Matt
