ERROR Need Help

My Server is not working at the moment.. I am getting an error. i have posted below... Any suggestions? I have restarted. The following error occured while trying to force a show using the force matix screen. also appears when trying to create or edit a show record.

(EDIT) This appears to be a problem with Cablecast. I am unable to change a show record or even force any source to any output. I can schedule a program to air and it does play (from the server)...I am waiting to see if it will play show after show after show... This is very confusing.

(Edit #2) - So far I can create and change the daily schedule and shows will play. I am unable to add or edit any show records. Unable to use the force matrix screen. It seems we will be able to be on-air over the weekend but Friday night was bit and miss for 3-4 hours.

Thanks

A potentially dangerous Request.Form value was detected from the client (DeviceID="</td,</td,</td,</td,...").
Description: Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted. This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack. You can disable request validation by setting validateRequest=false in the Page directive or in the configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case.
