Same error here, but only on one computer, the other is ok. Both installations are more or less identical: The laptop is always a little behind the desktop. If I add files, I'll do that on the desktop and then every once in a while I copy the entire set to the laptop. If there are files to be installed, this will always be done first on the desktop and a couple of days/weeks later, when everything proves to be stable, it will be installed on the laptop also.

Now I have installed 2015 on the laptop and here I have too many styles. Rebuilding the style picker results in the above mentioned error message.

On the desktop and the laptop there are two LSW files:
BBW-Cat.LSW 21.01.2015 09:30 11 KB
BBW-Sty.LSW 21.01.2015 09:30 6341 KB

The difference are date and time.

There was NO success with erasing the LSW files. The number of *.sty files is roughly 7900 files.
