Cannot access whole site when using any server from VPN provider Astrill

I simply get a page telling access is forbidden!!

This is quite frustrating as I am in China and have the VPN as standard and now have to switch it off specifically for Lingq.

This only started a couple of days ago.

Anyway ideas why anyone?

@UniqueView - sorry to hear you are having trouble with this. Recently we have experienced malicious attacks to our site. Now we are using some blocking tools to prevent such attacks in future. We are not 100% sure but your ip might be blocked. Would you send us your ip you are using for the VPN so that we can take a closer look into it and probably (if this is the case) unblock it: support(at)lingq.com. Thanks!
