Usb Device Restricted

[swiltshire]

Up Until Now My Usb Pen Has Worked Perfectly On My Computer Running On Xp Home But Suddenly I Have Been Prevented From Opening My Usb Device And I Get The Following Message

"this Operation Has Been Cancelled Due To A Restriction In Effect On This Computer. Please Contact Your System Administrator."

I Am An Administrator And Do Not Recall Changing Any Settings That May Have Caused This.

If I Log On Under My Girlfriend's User Account The Usb Pen Works Fine, So Does It On My Sister's Computer.

Does Anyone Know How To Remove This Restriction?

Thanks
