Request code for 1.6.5 and problems with Licence activation

This message is also in the Licence activation section, wasn't sure if it was the right place, hence also 'appearing' here :-

I have just downloaded SR 1.6.5 and requested a serial number, but on closer inspection (after 'poking' around on this forum) that version 1.5.1 should be OK with VRay 3.0, which was registered.

BUT after installing VRay 3.0, Solidrocks 'stopped' working, I pressed render, the Max render box starts then immediately stops and nothing renders.

Unfortunately the only reason I downloaded Solidrocks 1.6.5 and installed was I thought this was the version for VRay 3.0 (also waiting for a serial number for SR 1.6.5).

FYI ... Request code : SR165-FYYB-UY-9333-1608-0531 for 1.6.5 .... for serial number

thanks
