Yeah, I'm sure we can help here. All that means is that the drum template uses the Transient Shaper plugin effect to alter the sound. For some reason the TS is not installed on your system. The TS is an older plugin and may have been discontinued from the current SONAR bundle (I am not sure though... someone else would have to confirm). So if you bought Sonar recently and do not own and/or have an older package that DID include it then obviously Sonar can't load the plugin. This doesn't hurt the template of make it not work. It just means you won't have the TS affecting the signal (the template itself is likely older as well and they just haven't removed it from the included templates list).
The other possibility, if the TS has NOT been discontinued, is you did not install all the extra FX packages that come with Platinum. They are separate downloads/installers so check your Cakewalk account or Cakewalk Command Center installer to verify you have indeed installed everything. If not do so and try loading the template again.
IF you happen to have an older Sonar version that included the TS but simply do not have it installed on your current system for whatever reason you can do an Advanced Installation of Sonar which gives you a list of specific elements you can install (such as discontinued plugins) without installing the entire package.
Hopefully that helps.
Cheers!
