Power CMS and linking to other pages?

I have Power CMS 102, HTML Editor 2, and just about every other WebAssist product. Right now I am just concerned with the Power CMS, and the ability to link to other pages within my site.

After I start up the CMS editor and bring up a page with a section I want to edit, I select either an image or some text, I want to create a link to another page in my site, so I click on "insert/edit link", then click on "Browse Server", I am then presented with a page for selecting the link. However, here is where things seem to go wrong. I seem to be only able to select items, (images, pdf's, whatever) that are in the what I think is the "root" directory of Power CMS and the folder that was automatically created "files".

So the path seems to be files/ This does me no good if I want to select a page or other file say from the path store.php or availableDogs.php.

So my question here is how do I point Power CMS so I am able to let some users or myself select files or images as the link to.

My directory is set-up as mysite.com/ then root files, such as index.php, then other folders, and CMS,
mysite.com/CMS.

I think the product that WebAssist creates are good, some of the documentation is lacking, but other than than, excellent products. But if I can't create links or let other users create links, then Power CMS is just not up to par. So again, any and all help would be appreciated.

I have read every post on the Power CMS forum from page 1 through page 16, there are quite a few articles about this same question, I have tried all of them with no success.
