Hi guys,
I am having this problem after a video downloaded 100% the application shows that it is paused and when we resume the paused video there is a pop up window appears with a message 'Download failed
Failed to append/convert file parts, please check if the drive is full or write protected'.

I am using XDM App version 7.2.7 with runtime 1.8.0_151 on Windows 7.

I checked out solution on following thread .

https://sourceforge.net/p/xdman/discussion/xdmhelp/thread/a8904e78/

and by mistake I have also posted my issue with logs on same thread. I have tried the steps provided for renaming the downloaded files. but its not resolving the issue.

Attaching the logs again.

Apart from log outfile I am getting below exception on terminal.
