network error for apps but not browser

[natnov]

So I'm new to the Tab and Honeycomb, only had my Tab about a day (it's a 10.1 with the TW update, WiFi only, 16 gb model) anyway I can access the WiFi fine to use the broweer but suddenly today I can't use apps that need network access such as Pandora and I can't download or view my apps in the marketplace. I get a network error that sats retry or cancel. The only non oem thing I've done is put Netflix on the Tab....
Thanks in advance for your help
