Hello, question for anyone who might know. I have downloaded some of the tutorials’ source files and sometimes they do not work. They say ‘unexpected file format’. I’m running FL5 and these are FL5 files, actually, Fl5 r6, and I’m also running version 6. Some work and some others don’t, any suggestions? thanks, dave.

if you are using **flash 5** you cannot be using **flash 5 r6** because that version is from **flash MX** saving in **flash 5** format.

Your problem is that some files in the tutorilal section (specially in the **flash MX** area 😛 ) are in **flash MX** format.  
Or, you are a mac user.

Wich one?
