TZConnection and TIBDatabase they do not want to work together

Hello Experts :-)

I use TZConnection and TIBDatabase on my TDataModule.

TZConnection is responsible for connection for all my Zeos components.
TIBDatabase is used only for one TIBEvents.

This is what I actually do:

    DMabc.ZConnectionMH.Database := PathToFile;
    DMabc.IBDatabase1.DatabaseName := PathToFile;

    try
      DMabc.ZConnectionMH.Connected := True;
      DMabc.IBDatabase1.Connected := True;
   except
   end;

It used to work fine before I had to re- install Delphi and WinXP.

Now I get such an error:

SQL Error: I/O error for file: "my database file" Error while trying to open file The process cannot access the file because it is being used by another process.

These are my components' properties:

object ZConnectionMH: TZConnection
  Protocol = 'firebird-1.5'
  Database = 'path to gdb file'
  User = 'sysdba'
  Password = 'masterkey'
  ReadOnly = True
  TransactIsolationLevel = tiReadCommitted
  Left = 36
  Top = 8
end

object IBDatabase1: TIBDatabase
  DatabaseName = 'path to gdb file'
  Params.Strings = (
    'user_name=sysdba'
    'password=masterkey')
  LoginPrompt = False
  IdleTimer = 0
  SQLDialect = 3
  TraceFlags = []
  Left = 33
  Top = 72
end

What do I do wrong?
Why it used to work and now doesnt?

Thank you very much :-)

looks like your TZConnection opens db file with exclusive lock, check if there's some property that controls locks
