This tool will help to fix some (not all) of the causes of "sync is currently experiencing problems. It will be back shortly." message from Google contacts sync.

***IMPORTANT: Always do a full contacts backup before running this application.***
In ad-supported version you will need to run fix every time you see a sync problem. If you donate you will be able to disable ads and get automatic fixes for all newly added contacts. There is no need to recreate account.
Please note that if your sync was broken for a long time - you may have to manually confirm big amount of deletions during first sync after running this fix. See notification area for details.
If you are still getting an error after running this application - click Send Log button right after sync fail attempt. It will send me an email (you will be able to review it first) with error log data (if it finds any).
