Some Help Please

I had a wordpress blog on a .net domain (mydomain.net/v2), however the .net domain expired and we didnt get round to renewing it in time before the company slapped a large sum on top to renew it, so we decided just to get a new domain mydomain.info..

Obviously the new directory of the blog should be mydomain.info/v2 now however when i type it in it re-directs me to the old domain, i have went into phpmyadmin and changed sireurl under options to .info domain but that doesn’t help….

any idea how i can resolve this??
