Help! zlcient says -"No Disk"

[Crellion101]

I was having some problems with Roxio, and so I reinstalled it and this fixed the Roxio problem. I also have Zonealarm, which worked fine before. However after that Roxio reinstallation, I keep on getting an error message that zclient can't find "D" drive; it does this everytime I start Windows when Zonealarm boots up.
