i have a cannon elura 40 mc. its worked great for so long and lately it has been beeping and say remove cassette. at first i just thought it was the cassette but then it started doing it more often. i would put a brand new cassette in and it would do the same thing. and now it is happening. but i cant get it to push back in once it is popped out. it wont even slide down with no tape in. has anyone else had this problem? any advice is appreciated.

thanks
