I see the line 'THIS INSTANCE IS NOT VALID' in V-Cinema log file and the server doesn't work. What should I do?
It means that V-Cinema can't find proper USB dongle or it is built for different hardware configuration. Check if USB dongle is inserted in USB port and red indicator is on. If you have several V-Cinema packages, check if the number on USB dongle label is the same as in the V-Cinema zip file name.
