I tried my best to follow you directions for my Kindle Touch..
When I "Import data and reboot" from the Collection DB launcher menu on the KT, it does its thing and reboots, but I still have 0 collections.
If I run the (verbose) option, I see:
Process collection blah blah
delete empty collection
over and over again.. so it is like it sees the Calibre Collection plugin file just fine, but while it is processing it it can't seem to find the books the collection is pointing at..
