Hi Everyone, Thank you for Aeroglass, it works really well. I have Windows 10 version 1809, and have installed Aeroglass 1.5.10, but after every start up I have the pop up box asking me to save my free licence key to the clipboard. I have donated twice, and I have the donation key file placed under Aeroglass, in Local Disk (C:), and if I look in the debug logs I have invalid signature donation key. I do not know if I have done something wrong.
