Nokia Navigation :: Ovi Maps Won't Open In 700

I bought Nokia 700 2 months ago and I have been using Ovi Maps perfectly until last week, when after plugging my device in to my laptop I got a message that I should update the Maps application. I followed the instructions but there was not enough disc space, so the installation stopped. I unplugged the device and made some space, then plugged the device again and performed the update. After that, I can use the navigation application as well as the check-in application normally, but the Maps won't open from the icon. I tried reinstalling software, reinstalling the maps, nothing. I cannot find the Ovi Maps version as the application does not appear in the Application Manager. I open the Maps settings, I can see the maps I have installed, but no info on the version.
