Last night, we removed Viewfinder 1.4.2 from our software update service. Updating to 1.4.2 in registered installations sold directly by us were becoming unregistered as a result of a bug in 1.4.2. Customers who purchased through the Mac App Store are not affected.
If you updated to Viewfinder 1.4.2 and became unregistered, you can retrieve your license from our Lost License service.
We sincerely apologize for any inconvenience this bug has caused our customers.
Viewfinder 1.4.3 is now available in software update. While 1.4.3 fixes the unregistering bug, it will not cause Viewfinder to be registered again - you must still follow the instruction above to retrieve your license if 1.4.2 lost it.
