Problem with Write To Measurement File Express VI not writing to file if file was deleted after the first call (7.1)

Question

I'm using the Express Write to LabVIEW Measurement File in LV7.1.
I have it set to "Save to one file"  and have tried both "Overwrite file" and "Using next available file name" for the "If a file already exists" conditions.
The path/filename is passed into the function.
It works fine the first time around.  If the file is deleted before the function is called again, an error occurs since LV is unable to find the file.
I have had to stop and re-run my program in order to write to use the function again.
Since I am able to delete the file I assume it was closed but it seems like LV expects it to be there, even though the function was supposed to create/open/close the file...  Is there any way to reset this without stopping/restarting the program?
Since my application creates several files (only one using the Express VI) I am checking for the filenames and requiring that they be deleted (or a new filename be used) before acquiring data.  Everything has worked great, except for the Express VI.
Thank you,
David

Ok, I've edited the VI you posted to reproduce my error (this time with 8.0). 
I added a "master stop" and "start log" button.  To demonstrate my problem:
1.  Run the VI
2.  Click "START LOGGING" - c:\test.txt is created
3.  Click "STOP" - c:\test.txt is closed
4.  Delete the file c:\test.txt with Windows shell or explorer
5.  Click "START LGGING" - a new c:\test.txt file should be created but instead an error is raised in the Write LabVIEW Measurement File function.
Any ideas?
Thanks,
Dave
