Problems with Windows 8 allready installed Apps, can't open them

I have a 'little' Problem with Windows 8 in Paralles Desktop 8.
I am unable to open a few of the applications, with are already installed, including the store, contacts, news and some more. When I try to open the store from the W8 Startscreen, the green screen with the store icon appears for some seconds before it swipes back to the startscreen. I never see more than this. In the picture, you see what happens when I try e. g. the store to open from the 'windows applications' folder. The warning appears and says that some file couldn't be found. What could be the problem? The only thing I did was to make the virtual disc bigger and install the Adobe Creative Suite 5 and 6 some days ago before this started. And going back to an earlier snapshot didn't help. I would be pleased to open the applications - but what do I have to do?
