Google Play not functioning properly on galaxy s2

[butthewheels]

I've had my phone for under a fortnight and one day I just randomly couldn't d/l anything or update anything
I can get to it fine but when I select d/l it does the scrolly loading thing and just stays like that for as long as I let it, or about 6 hours later it will tell me that the d/l was unsuccessful.
How do I fix it? ... or should I just go back to the optus shop and ask them?

I have experienced this issue on multiple devices. A reboot has always solved the issue for me.
