Hello: I just purchased Flash Ad creator a couple of days ago. Aside from the fact that I can't change the ad or font size, it seems to be a nice program. I wished that the website had actually indicated that you were locked into a specific banner size. I don't know about other folks, but the current size is huge and one that I would never use on any of our websites. So, with that in mind, I decided to open the template in Flash and make the changes myself. I am using Flash MX and when attempting to open any of the .fla files, I get "Invalid File Format". What version of Flash do I need, or is there some other issue with the files. Thanks for any help anyone can give.
