Are you able log into the portal (https://portal.pixelfederation.com) and try using the Flash version to go to Valhalla? In Flash, Valhalla is in the main Scandinavia map.

If you don't have a PC, you can probably access that URL from your browser and sign-in. You might have to view the portal web page as a "Desktop site."
If nothing works, you will need to contact Pixel Support.
On your game screen, choose the Settings cog (Mobile, upper left corner; PC, upper right corner). Write down your Player ID and then choose the Support button. Scroll down past the white text box and choose a category from the bottom half of the screen.
Provide your Player ID, Mobile vs. Web GL, device, and problem details.
