Hi Tony,
Did you change/add the port setting for Sybase in the sybase.conf, changed it to another port than 2638? (Also Sandor said it was in sybase_db/servoy.conf but that is sybase_db/sybase.conf)
Also check the sybase_log.txt in that same directory to see WHY the database server won’t open (from either installation).
‘Can’t connect to the repository server’ has everything to do with your database server (i.e. Sybase).
Hope this helps.
