running Cat v3.32 h25Pro - no change
the catalyst happend to have a v4 dongle in it initially (due to availability) but was running v3.32 h25Pro
dongle was swapped to a v3(pro) dongle - procedure listed above - since v4 dongle was required elsewhere for a v4 mac.....

only the dongle was swapped - EVERYTHING else remained the same! - software, hardware etc etc....
the only thing that seemed to get lost was the sync ID's......

and im at a loss as to why the sync IDs would change - yet everything else was corect and remained the same...... patch, name, locations, serial codes etc.
