I tried, but none is working. I did publish 4 4K photo shows after purchasing the software, but after that the publish function of the software is not working. I have re-installed the software and tried again with my license and that too did not work. I updated all the drivers in my computer too. It appears that there is a counter in the PTE studio (normally used in trial version) that is keeping a count of how many shows I have published and when I exceed the hard coded maximum limit then it is not allowing any further publishing. Is this a possibility? What is the solution?
