Upgraded to Platinum from X3 last night and loving what I have seen so far. Instal was smooth and no issues, also upgraded to AD2. One issue so far, and this may be just me not having spent much time on it last noght, but I could not find the new amp sims, are these supposed to be located in the vast FX folder or are they FX Chains?

They are FXChains

Thanks Mike, had not got that far into it last night but suspected as much having not seen them as FX, got side tracked with AD 2 instal and choosing ADpacks.
 

They're based on FX chains, but were removed from the installer temporarily because the wrong versions were included initially. Please download the update that appeared today with the new amps, which have a modification to the FX chain structure and you'll be ready to go.

Cheers Craig, looks like my evening is shapping up for a rock out with the guitar

BTW... they are very nice.   
 
I'm particularly liking the clean versions, but the "brown" amps are pretty good too.   Haven't gotten to the higher gain versions yet...
