Something has changed in the PayPal interface. The address supplied is indeed supplied by our system. If it appears with the wrong address, are certain fields correct but just in the wrong area?
I have not yet gotten through to inspecting the differences in the PayPal interface as I am working flat out trying to get a new website up and running. However, you should be able to renew without correcting your mailing address in PayPal
Just go ahead and try it. Otherwise just bear with us, in about 2 or three weeks time I will have gotten round to fixing it (possibly on the new site).
Our membership system gives you around 6 weeks of leniency after membership expiry, so you can just wait.
