Yep, we certainly do. Now, if only some could be found . . . . 
When all else fails: you might try manually reapplyíng the latest firmware to the player–that can fix gremlins and software glitches that can develop. Easy to do (and it won’t affect your user content on the player)–see the firmware sticky thread at the top of this sub-forum.
Otherwise, you also could try re-formatting the player (not just the microSD card) itself, under the player’s System settings–that sometimes can fix unknown issues. Note that this will erase any user content–save any content you want to keep to your PC first.
A final possibility: you might try reformatting the microSD card using the SD Association’s own fomatting tool–that sometimes can fix issues, and there may be something hinky with your card. The Clips can be finnicky about cards. Again, save anything you want to keep first.

I’m just guessing as to possibilities–sorry!
