Vince,
One thing you can try is look to see where tf10lic.exe is located. For us it was in the file we downloaded. Once you locate it go to Run on your Start menu and type cmd in the Open field. Go to where tf10lic file is located using cd. On you are there type tf10lic /ResetDSN and hit enter. It will then ask you to select your system DSN. Then go and stop your Apache service. Stop your TF service. Once it has stopped restart your TF service and then restart your Apache service. Try you URL again and see if it works.
Regards,
Margaret
