Target Monitoring Tool

Hi guys. I’m new to Open AT and trying to get Q2426B going with Open AT 3.01. No luck so far. Target Monitoring Tool displays massage:
Trace L3RR Unable to find the string of the remote tace in the file ID 5074
Sample “Hello World” compiles and builds but “Trace HWL Arm exception 1 12c0a84 900” message is displayed in Target Monitoring Tool. Any ideas what is going on?
