Go to this link:
Go to global security settings.
Click browse for folder, go to your drive root (or the folder where your swf/fla is and select it. You should see that folder get added to the security exception list. Re-test tell me what happens.
I did that, and not only added the different domain names/websites that the ad needs to linked to but also added the root folder and file names of the flash files. Still doesn't work...
lol sorry I didn't read all of your post I sometimes scan over stuff... sry. So, can you paste the code or perhaps just email the FLA and I'll take a look? Better to past the code in here if possible. Thanks,
