Just updated my 'BetaTest' system from A35 to that A36
prealpha, then I did a poll to get updated echomail and
such and it failed. It got some messages from fsxnet,
but not retronet. Both did fail though. Here's the
Fidopoll.log from A35 followed by the same from A36.
Note that all times seem to be GMT, not local time.
This is due to dual boot with Linux.

Since I only upgraded, it should work, but didn't.
I install the upgrade to \nmystic and then use a
batch file to upgrade:
@ECHO OFF
REM up - upgrade mystic
C:
cd \nmystic
copy mystic.exe c:\mystic
copy mis2.exe c:\mystic
copy mis.exe c:\mystic
copy fidopoll.exe c:\mystic
copy mutil.exe c:\mystic
copy mbbsutil.exe c:\mystic
copy nodespy.exe c:\mystic
copy qwkpoll.exe c:\mystic
copy scripts\mplc.exe c:\mystic\scripts
copy scripts\mide.exe c:\mystic\scripts
cd \mystic\scripts
mplc -all

Anyone see what I might have done wrong to
cause it not to work the same?
