Cannot switch edition

hi all,
i cannot switch the edition.
when i double click on the “VP-UML Product Edition Manager.exe”, it says “Production Edition Manager is no longer required”.
while if i start the “Visual Paradigm for UML 10.0.exe”, i will be told that the 30 days evaluation is expired, and i cannot go on to change the edition by selecting “tools”–>“license manager”.
it’s embarrassing, how can i switch to community edition?
thanks

Please uninstall your current software, then download and install the Community Edition from the following link to solve this problem.
