From Indie to PRO srn problem

Unity Engine
1

Hi, I upgraded my licence to PRO. But I cannot figure out how to use my new licence. I deleted the Indie version but when I reinstall the old serialnumber is still present. Is there a specific file that should be removed from my library?

Thanks!

Delete the following file:
/Library/Application Support/PACE Anti-Piracy/License Files/Unity_v1.0.0.ilf

Then launch Unity, which will now let you register with your new serial number.

Thanks! That worked!
