Hi, I've only just installed the "Yamaha Expansion Manager" after receiving a ".ppi" file and inadvertently formatted my expansion memory with the loss of all my expansion files! I'm not sure why I did not foresee this misinterpreting the instructions. I imported the "ppi" file into YEM and selected the Tyros as target. I connected the wireless adaptor and YEM promptly transferred the file but warned that it was formatting as well during the installation which was too late for me to stop!
I now realise what a mistake I made in doing this believing that the YEM software would add to the already installed files. And seeing as
I no longer have the codes for the original packages have ended up losing some expensive packages because of a moments lapse in concentration.
When I was using the YEM software I saw no way to convert to ppf which I believe is what I should have done.
Just sending out a warning to other newbies not to repeat my mistake!
***UPDATE*** Went onto "Yamaha music soft" and fortunately found my expansion packs still available to download not needing any codes. Awesome!
