Getting Access Denied error when try to deploy metro app from VS 11 Beta

Hi,

When I try to deploy metro style app from VS11 Beta, i'm getting following error.

Error : DEP0740 : Access denied. This may be because the application state is locked. A possible cause is "RuntimeBroker.exe" retaining a lock on the storage data for your application. The workarounds are (1) Wait for the "RuntimeBroker.exe" to quit. This may take up to 6 minutes. (2) Kill the "RuntimeBroker.exe" process and redeploy. (Note that option (2) may cause loss of data.) 

Error 2 Opening file from location: F:\...bin\Debug\AppX\AppxManifest.xml failed with error code: 0x80070005. Access is denied.
 

Any idea, why?
