cant get past the elicenser

hello im planning to buy cubase10 pro with the recent discount but yesterday i wanted to try the trial version fist. i downloaded cubase10 elements trial and installed. i entered the activation code to the elicenser but i accidentaly deleted the license from the list. now no matter what i do (i tried maintenance and all the other stuff) i cant use my deleted code or activate a new one because im only getting the message ‘‘elicenser a license of the same type you are trying to download is stored in the selected elicenser already’’ and even it says its ‘‘stored’’ i cant use it.
i will be glad if anyone can enlight me about this issue
