Hi can anyone help me as I have not been able to get a reply from tech support. Have just done a clean install of X3 on a new laptop. Not sure how to get my pro channel modules of concrete limiter,PC4K expander and CA2A that I had in X1,2 do I need to reload original pro channel software. Also I notice my session drummer 3 is not picking up the 64 bit dll to start although this does show as a vst in my X3 plugin manager. Hope someone can help please.

In a given PC right-click and select Add Module then select the item you are looking for. This assumes that you have already downloaded, installed and registered the ones you seek. The Concrete Limiter and CA2A are separate downloads and will be available in your Cakewalk account along with serials and reg codes.
 
Regards,

This may also be a case where Alex' advice from previous threads is very relevant - Reset and Rescan your plugins as a first step.
