Internal Error: Sub-system: TDC, File: /quartus/tsm/tdc/tdc_accessories_analysis.cpp,

Hi Darkwave.. Thanks for the reply.

We tried deleting the db directory with no joy, but we have it working right now.

It seems to work with our "Dongle" license, but not the "Floating" license for quartus..

Very strange. Anyway, if we get a definitive answer from Altera to the cause, I'll post it.
