The magazine in my Panasonic SA-ht80 does not work?

Hello all, the magazine in my Panasonic SA-ht80 is acting as it is out of alignment , first does not open completely and when I feed the disk does not close up and in screen showes "error" and when I try to push in manually (by finger) makes (click- click) noise .
The bottom railings are out of alignment.
How can I fix it?
