Which version of PicoScope 6 have you installed? Does the device run with the PicoLog software?
Also, which operating system are you using?
If possible could you send the trace.xml file that you will find in the folloing location to email@example.com
Win XP: C:\Documents and Settings\[your user name]\Local Settings\Application Data\Pico Technology
Win 7 : C:\Users\<Your user name>\AppData\Local\Pico Technology
You will need to ensure that you can view hidden files and folders (through Tools -> Folder Options).
In the 'Pico Technology' folder you will find one or more folder names with a long alphanumeric name - in there should be a trace.xml file.
