In some rare cases it can happen that your IP dont change - EVEN when running OpenVPN properly as described above - in that case and only in that case, check your connection log (right click OpenVPN icon => "View Log") for a multiple loop of the following, or similar entries:

This is CPU/OS related only (nothing to do with the VPN) and can as example occur on high CPU load, a clogged up system or random softwares causing it, basically said, many factors can play a role in this. A first attempt to resolve would be to either try a simple computer reboot, or to start off by opening taskmanager and closing all unneeded programs to lower the CPU load (close OpenVPN as well and try a simple restart of it). 

Yet another much more versatile and 100% solution is using Viscosity instead of OpenVPN. Viscosity is an alternative software that solves this problem quickly and efficient. Viscosity has a fre 30 days trial Version.
