How do I upgrade "Rigid Light" from version 1.1 to 2.1 in a Subdomain...?

Permalink
Hi, I was wondering if someone can help me out at all. I installed Rigid Light website theme as a Subdomain and I tried to upgrade it to version 2.1 but it doesn’t recognize the URL because it is a subdomain I guess…? The main directory / URL updated fine but the subdomain does not work and it is still stuck in Version 1.1 and does not even acknowledge the update / upgrade that is available?

Tried everything even my Hosting company gave it a shot but no one can fix it or figure it out maybe someone here can..?

Any suggestions on this and how to fix it via the upgrade to 2.1 version in a subdomain would be greatly appreciated.

Thanks,
Whistler
