I had my application working just fine.  Today I purchased Telerik Rad controls for sivlerlight and in the setup they asked me to remove the trial version before installing the paid licenced version.

Since I did that, i now get this error in almost every one of my silverlight pages.  Can any pleeeeease help.  

unhandled error in silverlight application code 4004 system.nullreferenceexception: Object reference not set to an instance of an object.

Thank You

    did you try to uninstall the Telerik Rad controls and reinstall the trial version again?

    i would talk to the seller. probably you need to add the controls to silverlight as well.
