Parallels is not displaying icons correctly in dock

Hello,

I was using parallels with my Windows 7 bootcamp and I liked it. But I had to reinstall Windows. Now after I set parallels up the Icons are no longer working. They simply so up as the Mac default icon. I have no idea why its doing this. Everything else works fine except the icons are not showing. Please help.

Here is a picture:



that icon on the far right(next to preview) is supposed to be Visual Studio 2010 but as you can see its icon is not there.

thanks for helping
