migrating from 32 to 64 bit

Hi

I have moved from a 32bit os to a 64bit os and want to continue using a version of smartftp for which i bought a licence.

When I install the 64bit version and enter the licence key, i get a message saying that the key is not valid for that version.
When I try to install the 32bit version for which I have a valid key, it refuses to install.

What should I do please ?

Thanks
