Is anyone  else having  trouble with the option to store content databases in content folder? I've tried everything 

I can confirm there's a write error with it.

I tried everything but I cannot save any sequence in the content database. I run Nexus and the latest version of PSE. When I save a sequence I find it in the file directory but without any extension and not with PSE but the explorer. I can not load it and use it. But when I edit a sequence and test it everything works.....I just can not start a movie with it as It does only work while editing...once I exit the editor the sequence is lost.

@TRJCan you redownload and reinstall PreShow and see if it changed anything.  Sequences need to have the .pseseq extension and I'm not sure why yours don't.  You can manually rename the file for now to see if that works.

So now almost everything is fixed. I had to create the sequences in pse. Using the CV ones even with new extension did not work for me. Even editing and saving them within pse did not work.

Glad you got it working. Let us know if you have any other issues that you need help with.
