I have been into the waveform library this morning, no issues, although not to upload, which I assume was your problem, I was downloading.
A couple of things, for the Pico Staff (Mike/Steve?) within the waveform browser, some possible improvements
1. once you select a vehicle make, you can no longer search all makes, you must select one. You need to close the browser and restart. It would be nice to go back to "wildcard" search. In fact same thing for other fields, like ECU make ...
2. Be good to be able to search key words from the notes field too.
