[WriteLog] An unknown error occurred while accessing.......

[K2MK]

During the CQ 160 meter contest I am repeatedly getting the following 
message. A dialog box pops up with WriteLog in the title bar, a warning icon 
on the left and an OK button. The message says:

An unknown error occurred while accessing
C:\users\Mike\Documents\WriteLog\Contests\15 CQ WW 160.wl.

I searched the archives and saw the same problem described many years ago. 
No resolution was posted. Searching the internet suggested a problem finding 
a file location across a network. I'm running a local computer and the file 
is saved on my C drive. The message goes away when I press the OK button and 
has not led to any loss of data or program crash. I have autosave set to 
record automatically after every QSO. It has always been set that way. The 
message pops up randomly after every few QSOs although sometimes it waits 
for 20 or more QSOs before appearing.

I was operating the VHF contest yesterday and didn't see the message at all, 
however, I only have 40 QSOs.

The only change I have made is to upgrade to version 11.24J. I've never seen 
this message before with any previous version.
