TT5 aborts each time when navigates

[et01]

I've contacted TT support, but wish someone can help me also.
I just installed TT5 in my Dell X51v, pairing it with Globalsat 359 BT receiver.
The software shows where I'm after the GPS fix, but when I'm all set with the destination, then it returns to Start screen, TT5 is the only software I ran, after aborted, TT5 is out of memory, it is very unfortunate, can anyone had the same situation?

TomTom says I should have the application installed in the SD card, how did I miss this while installing?
