Web-PVR is not refreshing the cache

[Lorenzo Martinelli]

Hello!

I have not used get_iplayer for a couple of weeks, and this morning I 
started Web PVR on Windows.
When I went to refresh the cache I realised that WebPVR is not finding 
any entries.

This is the screen I get


The cache will auto-refresh every 4 hour(s) if you leave this page open
Windows users: You may encounter errors if you perform other tasks in 
the Web PVR Manager while this page is reloading

Force Refresh Close

What could the problem be? How could I solve it?

Thanks
