I've downloaded the latest QGIS version and I cannot add basemap. I installed OpenLayers plugin and while adding any map from list QGIS crashes. I tried to enable Google Mercator CRS first, yet it's not in the list of available CRSs. Does anybody know how to fix this and how can start adding basemaps? Or is it possible to add National Geographic map as a basemap?

You should probably use the QuickMapServices plugin instead: gis.stackexchange.com/questions/123227/…– HeikkiVesantoFeb 15, 2017 at 17:42

The Openlayers plugin is depending on EPSG:3857.
In QGIS 2.0.1, this is called WGS84 / Pseudo Mercator.
It is not necessary to set the CRS in advance, the plugin changes the CRS on its own if necessary. Enabeling On-the-fly reprojection might prevent crashing, or preloading some vector data from your part of the world.

Thanks, I've found Pseudo Mercator. Yet it crashes anyway, even if "on-the-fly" is enabled. And how do I preload some vector data from particular part of the world?– jowlisDec 1, 2013 at 14:20

If you don't have any from previous projects, Natural Earth offers vector data for the whole world. As an alternative to Openlayers, you can try the new TileLayer Plugin. You just have to investigate how the config file has to be written.– AndreJDec 1, 2013 at 17:07
In case a projection is missing for you could always add it yourself as custom projection. Just go to "Settings" -> "Custom CRS" and create your own.
For google mercator:
+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0
+k=1.0 +units=m +nadgrids=@null +no_defs
Although i believe that GoogleMercator is somewhere in the available CRS list.
