Rollover message causing NT Unresponsive

[LG]

I cannot do anything on my NT since when it opens up, it shows the message that "Thu Mar 12th is contract rollover for several futures contracts. . . " I can't click the ok at the bottom of that message, can't get rid of the message any other way, can't close any charts or click on Control Center at all. The only way out is to use Task Manager to end the program, restart the computer, and then the whole thing starts again.
Please help. Screenshot attached.
