I think that when you try to open the database in your preOpenStack
handler, the database library has not yet been loaded. Try setting up
a delayed call to open it e.g.

on preOpenStack
  send "connectToDatabase" to me in 1 second
end preOpenStack

on connectToDatabase
    global gConID
    put revdb_connect("sqlite3","DB_FLK.db",,,,,"my emailadress","my
password") into tConID
  if tConID is "" then
    answer warning "Problem creating or accessing database!"
  else
    answer information "DB_FLK Connected! Your connection ID is: " &
tConID
    put tConID into gConID
  end if
end connectToDatabase
