YIKES. . .Links quit working after a year!!

[reh]

What's happening?? I used flash pro 8 a year ago to build my site. I haven't had any problems until now! Identical problem on another site I built. Basically I have a hand full of buttons that work except the one that leads to my blog which is hosted on my own server ??

The domains are http://www.rehproductions.com &
http://www.lwbcmn.org

At either place on both of my computers in both firefox & safari. . .and my mom had the same problem on her PC?? How can they work for a year then have problems ?? It has to be the changing standards of Flashplayer 9
I found a little info about security policy changing but how do I fix it? I tried using a cross-domain policy xml file with no luck yet.

ANY HELP WOULD BE MUCH APPRECIATED. I'm spending a lot of money I barely have to promote my website.

Please be more specific, give some code etc...

I don't really know code much. I just know that for the last year I never had a button fail and now, off and on, there is one button on my site that fails for no apparent reason. . .only one, and it's the same exact situation on another site I did. I mean nothing has changed. It is the button that says blog . It goes to a different directory on each same server. These are flash sites. What can change or quit working besides compatibility with the latest flash players? Especially button specific like that??

Is it possible that a bad router in my home is causing this? I'm finding out that this problem is off and on now.

This is the cross-domain policy I used which worked to correct a different issue I had with another site.

Doesn't seem to have changed anything for my site.

I'm back after a year of wondering why my links sometimes work and sometimes don't. I now have more information. On certain computers the Blog link on rehproductions.com will only work if the www is in the address. These are not separate files. The blog button will not work on anything at rehphotography.com So for now I've simply redirected everything to www.rehproductions.com. But what is the deal? Also, if you go to http://www.rehproductions.com/the-di....com-points-to which is www.rehphotography.com/photography then the link works fine.
This is psycho.
