I have installed Premier pro CS3 as an upgrade from Pro 7

When installed it was listed as version 3.01 and when I checked for any upgrades there were some which I duly downloaded and installed.

This lifted the version 3.2.0

However I get a message that the upgrade to Device Central FLASHLITE3 can not be implemented as the file may be damaged and I should re-install it.

I have re-installed all three programs, Premier, Encore and On Location but still get the same problem.

Any advice please?
