update does not work

hi,
can somebody help me to solve this problem?
from last week whenever I try to install the vps , it shows me a message about failure in downloading the package.
I did it again and sure that there is not a problem in download but the message appeared and the vps didn’t work.
My Avast is not updated , please guide me to solve the problem.

Is this the FULL VPS being downloaded , this file http://files.avast.com/iavs5x/vpsupd.exe ?

What is the full text of the error ?

May it be related to this ? It started Sunday.
