broke on second launch

Downloaded and used the app yesterday, seemed to be working okay - but today when I ran the program it will not search for any items I put into the search field. The buttons for switching from KM to MIles and what ever else is in the tool bar will show up for a brief second when I am typing in the search field, then dissappear.
It is stuck on my home location, and will not let me search anywhere else, so it is of no use. For a moment using it when I first downloaded, I was ready to buy the full version.
If they can get my version working flawlessly then I still would consider a full version.
