My problem seems similar to the one in this thread:
http://empegbbs.com/ubbthreads/showflat....true#Post245047
However, every upload and sync, etc. works fine on USB.
Ethernet sync works fine as long as there's no change in the playlist. As soon as I, for instance, change the play order, ethernet sync crashes upon intialization (emplode says "while writing player configuration"). Upon reboot, the player is rebuilding all the music databases for ages and then works fine.
Yes, I checked the bootlogs and they looked unsuspicious (I can post them, if you want), yes, player and emplode versions match. I've used ethernet to upload for ages now and never had a problem. I'm not aware of any change that I have made that could lead to a crash of ethernet uploads as compared to USB uploads. Actually, I'm not aware of any changes at all since the last upload and now.
Could a change to the network infrastructure (software or hardware wise) here at the university be to blame?

Sorry, the version on both player and emplode is 2.0 final. I checked the config.ini file and it looks perfectly normal. I actually could delete an empty line/carriage return at the end of it and write it via ethernet without crashing. Thus, it takes re-ordering of a playlist or uploading tunes to crash the ethernet synch.

After some further crashing and restoring via USB, I gave up and left the sync problem (I didn't have any files left to sync, LOL :-)
Interestingly enough, a few weeks later, I tried to sync again with ethernet and it worked fine. So either it depended on the state of the player, or there were general network problems in the university network at that time, which only manifested themselves in the described way.
Either way, the problem is gone without any changes on my part whatsoever.

Glad things are OK now.

Doesn't make me feel confident about the quality of the ethernet driver though
