DT to Go many Error-Messages on iPhone

since I installed DT3 and DT to go was updated, I get many times a message on iPhone, hat Database.sqlite cannot be opened.
I think, there is something wrong…

I confugured for local sync.09

Try this…

  1. Press the Help icon in the bottom toolbar.
  2. Go to Appendix > URL Commands > Performing Service Tasks .
  3. Press the Execute link under fix .
  4. Quit and relaunch DTTG.
