Unable to queue the asynchronous operation because there is already an operation in progress.

Hi,

 

I have been trying to capture data from Tektronix DPO2024 using Labview 2013 (32 bit). Everything was fine. But suddenly I get error as -

 

"VISA:  (Hex 0xBFFF0039) Unable to queue the asynchronous operation because there is already an operation in progress." I read the threads, but did not get solutions. Any help will be appreciated.
