HALion 3 + HALion One + Cubase 5

Hi, I have HALion player v3 and was using this with Cubase 3. I am the process of moving to Cubase 5 and would like to keep all my projects that use HP3. I have installed and registered v3 on the Cubase 5 machine and the standalone player works fine but Cubase does not see the VST instrument although.
HALion One shows up fine, but not HALion Player3 although the dll is in the vst folder.

Please help

Ok so it turns out I just needed to click “update” and “updating plugin info” on the plugins info screen and halion3 returned.
