I tried the above examples with Mathematica 7.0 on a 32-bit Windows XP 
Pro SP3 machine and got the same Missing["NotAvailable"] results. 

I doubt that your installation might I have been corrupted because 
ChemicalData have never been used on my test machine (everything had 
been installed anew last week): it took several minutes to get the 
initial process completed, displaying the waiting bar "Accessing 
server...", "Initializing...", and the like, and nothing at the end :-)
