I've uploaded a new version of BlipLR that fixes an issue people were having with location data in Lightroom 4. It seems that Lightroom 4 strips location data if the metadata panel isn't displayed in the export dialog. I had it hidden because it seemed kind of irrelevant for BlipLR, but I suppose that some individuals may prefer to have the choice to strip out metadata.
Anywho, the new version is available to download now from the usual place.
