TomTom Upgrade Version 3 to 5 errors

Hi

Can anybody help with these two issues:

I have just upgraded to Tomtom v5 IPAQ 3970 Wired GPS using the upgrade kit and I am getting the following errors :

1: When I turn on my IPAQ put in the password and it opens up, a pop up screen appears with the following Error message :

Cannot execute \\.\Notification\namedevents\eventwakeTomTom, if I ok it, it seems to be ok. Why do I get this and how can I stop it happening ??

2: When I plan a jouney and run the Demo of that journey, using MotorWays if I am using a long stretch of Motorway the screen freezes and I get a White Arrow appearing pointing forwards, and an arrow coming out of the side of the main arrow indicating a turn. I basically loose the moving Location Arrow/pointer that shows me where I am on the road. This also happens when I am actully using it to navigate as well. This appears to only happen on Motor ways. When I eventually say turn off the motor way it un-freezes and returns to normal operation..

I've not heard of hese before but have you tried downloading and installing the latest update v5.1 from tomtom? This may solve those issues.
