Paypal payment will not complete

[TMBS]

Hi

 

I'm trying to book some train tickets on trainline.com. I can add to the basket but when I click on Pay with Paypal it opens a new window which I select my card and click continue but I then get the following error:

 

Don't see the secure Paypal browser? We'll help you re-launch the new window to complete purchase.

 

The window then disappears and I'm back on the Trainline checkout page having not bought the tickets.

 

I've tried Google Chrome, Internet Explorer, I've allowed pop ups and redirects and have tested on our server too which is unfiltered but still no joy?

 

Anyone have any ideas?

 

Thanks
