License Error

[yiuin]

During installation I get the following error:

ERROR: LicenseHandler::validateSerialNumber: serial number is of a wrong length! Expected 13 characters!

I downloaded and put the license file directly where it should be.

The serial number must be of format xxxx-xxxxxxxx
With a copy/past often blanks or other invalid characters get included into the input field.
If you cannot resolve that use license method 'Choose alternative activation' > 'Use a license file' rather than activating with a serial number.

Hubert.
