Xbox 360 media extender freezes after video file delete from HTPC external HD

I have tried deleting and reconnecting Xbox extender, creating new folder for videos in external HD, reformating Xbox 360, and plugging ext HD into different usb.

Deleting TV shows from internal drive works fine.

When I delete videos from external drive they appear in recycle bin

Sometimes I get error that recycle bin is corrupted on internal drive that has recorded TV. I have run
cmd rd /s /q C:\$Recycle.bin on all drives and I have deleted all recycle bins to no avail

Is there a way to refresh WMC7 without doing a complete reinstall?

Any advice is appreciated
