Floating Client Lost Contact With the License Server

It is possible for a floating client to lose contact with the license server. Some possible causes for this could be:

If the problem is resolved and contact is reestablished with the license server, the floating client GeneLinkerô will not terminate (a message is displayed).

If the problem is not resolved within ten minutes, the floating client GeneLinkerô will terminate. Please note: any running experiment will complete even if it takes more than ten minutes and all data is saved.

3D Plots Crashing

The most common cause for crashes when displaying 3D plots is having older video drivers. To determine what video card and driver you have, and to update to the latest driver:
