Yeah, I'm still waiting, too! No chance spending money for the pro version if half the product fails :-(

Just made a fresh download of 1.4.6. Want to download 10760 bookmarks (nested folders) from server to IE11 on Windows 10-1709 64bit.

Same error as before. Download starts, after maybe 1 minute error pops up:

      

Did send error report ("Yes"). After that only 244 bookmarks have been downloaded:

     

Same error occurs when I manually delete all bookmarks in IE before downloading.

Please get this repaired! I need it so much (came from Xmarks).
