I reinstalled my mac OS X (Yosemite).
After that I get a message every time i startup the imac including automatic startup doit.im

"Er is geen programma ingesteld om de URL 'doitim://launch' te openen" (see attached)

(translation: There is no application to open the URL 'doitim://launch')

And i have to login by hand every time.
In the preferences I selected 'Start at login'.

Please can you help me?
