Hello Raymond!
The second message says that it "could not find a license for Vienna Ensemble Pro". Do you have VE Pro installed on your computer? If yes, it might help to uninstall it. Since you have written that you have copied or moved .dll files, it also might be nexessary to look for remaining files called "Vienna Ensemble Pro.dll" and "Vienna Ensemble Pro x64.dll" on your computer and delete them.
Best regards,
