Help, lost my dongle driver CD..

Hello, I'm using High Performance workshop 4 on my Office Desktop PC with an USB Dongle as a license key..

Now I want to work on my laptop as well, I installed everything and averything was  fine, but after 64 days the trial period is over, now it asks for a license key..

As far as I know dongle version permits to work on more than one computer, Unfortunately I cannot find the installation CD where the dongle driver was...

I also searched the Renesas site but I could not find it as a download....

 

any help?  Thanks
