ENDIAN Firewall - openVPN on Windows XP

Hi everyone.

I have an Endian firewall 2.2
I recently setup OpenVPN 2.1(EndianVPNClient-2.1-setup.exe), and it work fine in Win7 or VISTA, but i having trouble in WinXP.

Let me explain better, when I start the vpnclient (During the installation I had only one warning about compatibility with XP sustem of Tap-Win32 Adapter V9), The software seems to communicate well with the ip public address and running up to show on screen (connected to "public ip"), but at this point when I check the connection, this does not work, because if I do "ipconfig" by prompt, PC(only XP) I display an address "169..."
checking the log of the software I realized that an error is reported.

someone help me, please
