[Dx4win] IO Error 103

[Emily Thiel]

Dear all, I am merging ADIF files from 3 operators into one DX4WIN file.  Every day or every few days, they send me their latest log.  I have done this for the last special event without any trouble (in Windows 8). This time, it has gone flawless for 3 weeks, but now I am getting the IO Error 103. Just happened that I upgraded to Windows 10.
 Normally, they send me their ADIF files by email.  I just download the files to my desktop, and leave them there. (Not opened).  I do a File Import, File Import, and choose their specific ADIF file from my desktop.  This is when I get Error 103 this time. If I try to import in the current special event log, or if I open a brand new DX4WIN file, the same hanging persists.   However, from a new DX4WIN file, I am able to import their old files that is still on m desktop.  Two of the ops sent me their files, and neither can be imported.  I assume the same will happen with op 3. This problem just started last night.   What can I try?? My laptop now has windows 10 (installed during the WPX wknd) All the previous imports were under windows8.  Any setting that I should  change or beware of in Windows 10??At this point I assume it is a Windows 10 issue.
Thanks in advance, Emily Thiel, P43E
