Not sure if I can add much more to this. My old installations of v7,8,9 and 9.1 all went into Program Files\JRiver\Media Jukebox as I over-installed up through the versions. I still have that directory with quite a lot of files and folders in it, although they dont seem too important - skin graphics, thumbnails etc. My new installs of 9.1 and subsequently 10 last night all went into the new default of \Media Center (aside: I assume I can safely remove the Media Jukebox folder now?).
My winXP control panel lists Media Center 9.1 and 10 for uninstall, both with a size of 30MB and last used 12/12/03. Ive been using v10 today (13/12), but I dont know what that date means. Id be happy to uninstall/reinstall or provide any more info if it would help.
Holden - if you're desperate you might try restoring your v9 code through v10 and seeing if that gets you to the $10 price like it did for me. Or perhaps try 10.0.13, which I think was the first build to incorporate the new price. Might be best to wait for a new build, though. Without wishing to open a can of worms, do we have any idea how long the 'limited time' price lasts? days/weeks months?
