Updated my Lightroom to version 5.7 [991162]. But I keep getting the screen that a new versio is available.

After a notice of a new update for Lightroom I downloaded and installed the new version, 5.7 [991162].

This new version is showing when clicking at the System Info bar in Lightroom. But every time I start

Lightroom I get a pop-up that a new version 5.7 [991162] is available. I also don't get to see the new

releases like HDR merging in my menu when clicking on the Photo tab.
