Try using a different drive... external drive that is PT compatible. Make sure if you have upgraded the PT version and that you upgrade all your plug-ins as well. Start with a new session... set it up for your computer (Buffers, inputs, outputs, playback engine, etc, etc, etc) and then save it as a template in the In/Out library, as well as the actual session file. Once you get to the "no click" point use the template for everything you need and it shouldn't hiccup anymore.

Most of what I have read/seen about cracks and pops had to do with Hard Drive or PT settings.
