VISA: (Hex 0xBFFF0015) Timeout expired before operation completed.

I am new to lab view and i am using a Tektronix 3014B o-scope, I downloaded the driver pack from the NI site and am connecting through TCPIP on a local network when i first ran the examples that were included it worked fine for only 5 runs then i get this error and have not been able to get the examples working again. No changes were made when this error happened.

i have attached the error dialog box. when i tryed to trace it down i think it is comming from the VISA read but do not know how to fix.

Labview 7.1

Thanks,

Jared

Have you tried power cycling the oscilloscope. I have had this issue with a tektronix 3034. If any of the settings on the front panel of the scope are changed while the driver vi is running I have gotten this error. The scope does not automaticlly lock out the front panel controls when it is being remote controlled. Every time this error has come up I have had to power cycle the scope.
