I have a Kingston Micro SD 1 gig memory card for my Motorola SLVR l7c which...

...used to work great.? but now it freezes up my phone every time I try to listen to my music on it or click on my 'sounds' button. It's not my phone - when I take the memory card out my phone works fine.

I need help - what do now?

I think your card got corrupted.
Check it on your computer and check it for viruses as well.
