License Problems on Max 2010

I have 3ds Max Design 2009 installed with the Vray 1.5 SP3a + Vray RT. This Max is working all ok.

I received the new version of Max 2010, and as always, installed the new version without uninstalling the previous summer. To test.

This new version installed Vray 1.5 SP3a + the Vray RT, the installation of Vray, I chose to not reinstall the drivers from the dongle as it had done all the upgrade process for RT.

Only now when I try to use Vray in Max in 2010 says he can not obtain the license giving the numbering error -98.

How can I overcome this problem, since I have both versions installed for testing and presenting to my clients.

Is the license server running on your local machine, or is it another machine on the network? Also, did you install 32-, or 64-bit versions?
