A quick update on the "Commodity Not Found" Error dialogue problem.
I thought I fixed it with a re-install, then this morning after the BPC took forever (alright I'm exaggerating maybe 5-10 minutes) to parse the initial market update, the commodies list only went up to Hydrogen Fuel.
Suspecting the initial Parse I shutdown the tool, killed off any processes, then restarted and did a Force Data Download, problem went away, it seems as though it may be related to the Parsing of the first data load, I wonder if it's related to the number of known systems too?
Anyway, happy hunting.
