Permissions of Windows_7.pvm

Hello,

I have a big problem with the Parallels Mounter 7.0. I got only read permissions of the Windows 7.pvm - file. It's not possible to transfer data from VM to my imac. The Finder says I have all permissions for .pvm - file but after mounting with the parallels mounter I got the message: only read permissions. I checked the recommended configurations in the VM-Configuration. Any ideas what is the problem?

Thanks!
