My roodial license code is not working

my roodial license code is not working.
what happened is that roodial with version 2.1 of reextend was working fine
then it decided to stop working. I would not get it to work.
I tried entering my license code into license manager but it says invalid
I then upgraded to 3.3.0
3.3.0 will not take my license code either
who can help me with this ?
thank you
Dennis

i purchased this license in 2022

Hi Dennis,
Are you using the same RPI as when you first used your license code in 2022? If not, you first have to revoke the license from the old RPI, otherwise your license is still in use on the RPI of 2022 and you will not be able to use it again on a second RPI.

acutally this is my bad - looks like I bought a yearly license that expired.
