Need install for Backup Exec 2010 R2 (not r3..) - anyone hellllp

Hi All

Have serials and licensing for backup exec 2010, i have just reinstalled one of my nas boxes which houses all our company data, the only agent which works on this is Ralus 2010 R2...

I have recently reinstalled my media server, and went to symantecs page - entered my license key and can redownload the installer... the problem is, the only available version is now R3.

Anyone have any suggestions as to how I might be able to get R2?  If i install R2 and install to R3 once the agent is connected - it works fine, i just need to reinstall with R2 first : (

thanks!
