I just updated HM2 to version 8162,
then updated notecaddy to latest version too.

Then i created download link email to my email, and downloaded the latest notecaddy edge ultimate package zip file.

Now when I tried to import the latest notecaddy edge ultimate zip file, it always stop halfway and HM2 force close.

The last few lines of the log file showing this:
