Thanks for the report!
1) Have you tried http://cintanotes.com/files/debug/Cinta ... _Beta0.zip
2) Could you please provide a log of a failed sync? Please send it to firstname.lastname@example.org
How to take a log:
1) Run CintaNotes and activate "Help/Debug/Debug Logging"
2) Try to repeat the problem
3) This will produce the file named "log.1.txt" (either in CN folder,
or in %APPDATA%\CintaNotes) - please send it to me.
Please note that this file may contain some of your private data, such as tag
names (but no passwords). You may want to edit the file and remove this data
Hope this is not too much to ask, this will make the problem evident
and we'll be able to fix it quickly. Thank you!
