ITunes 10.5 Dev Beta Windows Problems

I am getting issues after iTunes 10.5 installation. I can't see the Diskstation on my network when iTunes is installed. But since it is the recently changes I made, I deleted it for a while and then the Diskstation is visible. Also, I tried installing iTunes 10.5 on my laptop that runs Windows 7 32-Bit but it doesn't seem to work. If this some sort of a bug, how can I fix this?
