As far as I can make out they are all taken from the main Profiler factory content so you should have them already. If there are any prand new ones these can be saved into RM and transferred to you profiler as normal.
The original versions of these Rigs are available in Rig Manager with the same names. The Rigs were adapted to the capabilities of the Plaxer e.g. received FX 1/FX 2 and Effect Button I assignments. Could be that a Natural Reverb has been replaced with a Easy Reverb. But the core sound hasn't changed.
