st: trying to upgrade

Title: storing many estimation results

I have Stata 8.0 and I tried upgrading to 8.2 by typing "upgrade all."  Everything downloaded successfully, then I typed "update swap" as instructed.  Stata closed and then reopened but with the error message

 

Access is denied.

. C:\Stata8\

unrecognized command:  C

 

The path is the correct one for Stata on my computer.  Any thoughts on what is going wrong?

 

Thanks,

Farzad
