When dealing with technology, inevitably not everything works the way we expect it or want it to. MyExperience offers a few ways of tracking down errors, which are described in the Troubleshooting section of the How do I? documentation on the Wiki.
If you are experiencing an issue with MyExperience, the easiest and fastest remedy may be to email the MyExperience Users mailing list (sign up here, view archives here) with a description and log file of your problem. The log file can be found on your device: \Storage Card\MyExperience\MyExperienceLog.txt.
