If you downloaded primo from my guide then you have the same licences as me.

Besides I believe if the licence is missing then the content shows as inactive and is ignored.

The licence file is UNAV_Learning_Navigation_2011_Q4.lyc

And i'm trying to use a 2012 file

Should not make any difference.
License files are not commonly updated on a yearly basis (as are maps, etc).
Besides, as FBF said earlier, if it was strictly a license issue, the content would simply not be active.
A license (or lack thereof) does not cause a spontaneous reboot or crash in WinCE based on what content is there or not.
Something else is going on.
Now, if certain license files are inappropriate for a certain iGo/Primo release, that could be different.
Try removing UNAV_Learning_Navigation_2011_Q4.lyc and see what happens.

Before reading your answer, i just copied again the LICENCE FOLDER.

I'm using the device for 10 min now and no reboots. Crossing fingers :-)

I'll let you know later if that was the problem or not .....

Ok, playing with it for hours now, and no reboot at all ....

So problem solved? Maybe?

Yes, it seems to be.

Thanks to all for your help.

( i can't edit the title of the thread).

According to the OP;

I found the real reason for the reboots of my device when i put an *.hsp files.

In fact the device stops rebooting when i delete these lines in the sys.txt

[route.histspeed]
enabled=1
show=1
