Hi Susan, 

Where are you trying to download the driver from?  
If you are getting it from our Promethean Planet website, make sure you are logged in before going to the download section. 

Alternatively use our Knowledge Base to download without having to login. I am copying the link here for convenience, assuming it is the Promethean Board driver you are trying to download. 

I have created reference 00463431 in case you want to ring up our Technical Support.
