BB Bold :: Can't Connect To App World

I've recently experience water damage with my phone and had to claim off insurance. The new phone I was given had a fault and I was told that this is very common with refurbished phones which is what you are given when you claim a new phone with insurance with my network.Today I got my second refurbished phone and am currently trying to set everything up i.e.. The new facebook, bbm, and various other apps I've lived with for a year on my old phone.The problem I'm faced with is that every time I try to download anything via appworld, it comes to a certain point, mostly when trying to log in or sometimes it gets as far as starting to download yet not further than that, the screen freezes and pop up announces that:'blackberry app world is having trouble connecting to the blackberry app world server. Verify your network connections and try again'So..Is this a fault in the phone maybe because it's a refurbished phone and therefore not reliable or truly 'new', or is there anything I could do/try to get some apps!?
