Posting to wordpress - What is the URL?

Hi Heros! 

I have a set of learning modules that are all linked, yet separate.  The client wants them to be individual, but be linked. 

The way I was doing it was to publish a module to wordpress and then by looking at the published URL I could guess the rest of the URLS to then paste them in as a link in the last slide of each module (so it takes you directly to the next one in the series). 

You can see what I'm talking about here... launch Session 1.

I've already dealt with the browser clearing cache issue, I'm even testing on totally naive devices and I still can't figure out why sometimes it works and sometimes it breaks. 

I had these all published in Storyline 1 and it worked fine. THese are now in Storyline 3, and it appears buggy. 

I'm using this plugin to load the files into wordpress:

Any trouble shooting help would be great. 

I guess I'm really unsure how a storyline file generates a URL when it is launched.... and if it is always generating the same one. 

Thanks!
