I'll try the command prompt approach (never did that so I guess I'll be stumbling my way through it) with the heightened error messages setting and see what comes out.
Giving this a little thought, I wondered if some entries are too long ... and may be overflowing a buffer? Most are brief but some have 3 or 4 lines worth of information. (I loaded the keys file into a spreadsheet, using "=" and ";" as cell splitters. scrolling through the file looked fine -- nothing grossly broken up or out of place.)
On the other hand, maybe the file is fine but
VLC has a bug reading through the keys file? Maybe it has a buffer issue or something else that messes up?
(PS. I'm not looking for bugs, but I have to keep signing in when trying to post ... like there is a 5 minute timeout. Can we fix that too?
)
