The demo license doesn't let you enter dates in months other than November, December, January, and February in any Business Central clients.
Hence the reference to ??11*|??12*|??01*|??02 in the errormessage: 11 and 12 refer to November and December, 01 and 02 refer to January and February.
A demo license is what it is... it grants you the right to check functionality.... it will not allow you to run a full fiscal year.
