Which error are you getting?
"STATUS 910 MISSING PREVIOUS OR ILLEGAL GENERATION" is one that I've seen; although I went through a different problem. My gens were all being uploaded - but one gen in the series would get lost in transmission.
I'd suggest making a copy of the directory (or renaming it) and then setting up a clean directory and start the client over from scratch in the clean directory.
Ask Howard and Elena if they'd like to see the corrupted data from your directory - and follow their directions for uploading it, if they do.
