I installed the full version of Adobe Flash Professional CS5.5. After that when I reopened the application every time it asks for new serial number. I have 7 serial numbers with my product. I gave those serial numbers one by one whenever it asked. The serial numbers are completed and it shows an error that "This serial number is not valid for this product". Flash Pro is not loaded. Then I install trial version. It also shows the same error and continue to use as trail radio button is in disabled mode. Now What can I do? Give me any solution please... Sorry for my bad english...
