Unhandled exception at 0x778e8c39 in Skype.exe

Hello,
I am a Skype user. This error suddenly appeared in my screen that said, Unhandled exception at 0x778e8c39 in Skype.exe: 0XC0000005: Access violation writing location 0x00000014. I don't know about this error.
I saw this error once, but I just ignored it since it did not display again.

Unhandled exception at 0x778e8c39 in Skype.exe: 0XC0000005: Access violation writing location 0x00000014.
Since I experienced a power failure, I did not manage to shutdown my windows XP home edition PC, the mentioned error message always pops up my screen.
I am not quite familiar in computer software troubleshooting, but my first approach to this error, is to reinstall Skype client software. After with my installation I rebooted my computer, same error message appeared on my screen whenever I will use Skype.
Please share some solution to this error.
