| - | This FAQ should be the first place to check for answers to your questions. Many times the answer is hidden in the mists of our [http://groups.yahoo.com/group/jmriusers Yahoo group archives]. Hopefully this page will help clear that mist!

| - | ==How can I upgrade?==
| + | |
| - | | + | |
| - | Every release of JMRI is carefully tested to try and ensure compatability with previous releases. To quote Bob:
| + | |
| - | | + | |
| - | Backups are always good!!
| + | |
| - | | + | |
| - | Your config files, roster, etc, are stored in ~/Library/Preferences/JMRI (That's your own Library folder, in your home directory) If you make a copy of that, you've got everything that might get damaged if something Really Bad happens. But nothing like that is _supposed_ to happen; since JMRI 1.0 all formats have been (and will be, I hope) backward compatible. Note that they're not _forward_ compatible; if you create a new panel in N+1, you might not be able to read it in version N (or you might, there are just no guarantees)

| - | ==No Loco Detected==
| + | |
| - | With thanks to Paul Bender for the following notes:
| + | |
| - | | + | |
| - | Basically, the error "no loco detected" means that the decoder didn't
| + | |
| - | respond when the command station sent out the programming request. On a
| + | |
| - | Lenz system, this is the same as getting an "Error 2" when programming
| + | |
| - | from a hand held throttle.
| + | |
| - | | + | |
| - | One possible cause of this is that the CV requested isn't actually
| + | |
| - | defined in the decoder. See if you can read the problem CV using a hand
| + | |
| - | held throttle. If you get the same result on the handheld, then the CV
| + | |
| - | may not actually be defined.
| + | |
| - | | + | |
| - | This message may alsoresult from a bad connection betweeen the locomotive and the track --(dirty track, dirty wheels). Try moving the loco by hand to determine if the problem will resolve itself. Clean the track and clean the loco wheels.
| + | |
| - | | + | |
| - | ==Timeout talking to command station==
| + | |
| - | This message is saying that your command station and JMRI are not communicating. Typical causes are incorrect 'com' port settings, baud rate, and other arcane H/W stuff that is discussed in, at present, various different places unfortunately. If the program is starting up, but the programming options are 'greyed out' the [[JMRI Preferences setup]] page may be able to help.
