I just found this fix - maybe this will work for you:
###INSTRUCTIONS FOR HOW TO CLEAN YOUR CACHE###
Navigate to this directory: C:\Users\**Your user name here**\AppData\Local\MSDN Reader\MsdnReader\
and delete the 'Cache' folder.
On XP or Server2003:
Go to C;\Documents and Settings\**Your user name here**\Local Settings\Application Data\MSDN Reader\MsdnReader\
3. Restart the MSDN application, it should begin syncing and you should see the actual data.
Again, please let me know if you still run into problems.
Thanks for your patience!
