navigami

Dear Michal,
I serched some GPS application for my new GPS Enabler HGE-100 and I found out, that navigami is one of the best ones! (Really) But I have a problem with installation. The HGE-100 runs with software "GPS Location" correctly. But, when I run the navigami the program ask me about connection (povolit připojení?). I press OK. The GPS Divice is AT5, Connected, Baud Rate is 2400 - everything looks good and connected. However, I can find no Satellites for tens of minutes (it write me "Please wait") and there is no Position, too.
Do you have any explanation of this problem?
Thank you very much
Pavel
