Hi Miguel
You are probably having the same problem I had
Connect your phone per USB and mass storage. Open the "drive" file. If you don't see a "maemo" file that is the problem.
The solution...
Go to your main hard disc where the program was downloaded from the internet probably c: and open Program/sygic mobile maps/drive/ and copy the "maemo" file. Paste it in the "drive" folder on your device, restart it and the program should start. By the way, if you try many of the reprogram ideas in this forum and something goes wrong, all the original folders are on your PC as backup.
