The folders are still there but all account
settings + emails were deleted and replaced
with default settings, 6 accouts are gone

While 2.x worked fine with large amounts
of emails 3.80 was always showing that
it had problems to handle 300k+ emails,
it took minutes to start the software

Anyway...this should never happen, 1 account
can get lost...pc crash while data are written,
file corrupted...happens
But this one means that the software tried to
access about 20-30 files when something
went wrong...sorry but this is just stupid
