Credits problem

So like credits are supposed to be renewed every 24 hrs right? idk. but anyways mine arent renweing like they used to. and also, you know how when you run out of credits that little window pops up to tell you something like "oops you ran out of credits"? That keeps popping up after i use the free model too. i was using roleplay v1 and after each response from the AI, i got that little window. I think its a glitch. Can the creators please fox this problem?
