Redline
If the app stopped responding, displaying tasks or loading at login, you most probably caught an error.
There may be crash reports and logs that could quicken the process of fixing it.
Collecting crash reports
Open Console.app via Spotlight or going to /Applications/Utilities and opening Console.app directly.
Select on the left sidebar Crash Reports. Then in the opened list select an item (crash report) which name starts with Redline, then click on Reveal in Finder.
Attach this crash report to email and send it at redline@vanka.me with a short description of your problem.
