I posed the following prob. on Flash Player Forum and got the response to move it here, so here goes.
Problem: uploaded a revised website from CS5. Orig. site was created in CS3, revised in CS4, AS2 (working on updating to AS3- but not in this revision.)
When go to site: "Flash Player is required;" just to be safe I downloaded the most recent 10.1 "again", installed, no luck. Tried FF and Safari- same results. (History had been cleared.)
Checked my publish requirements and tried again: no luck.
Dropped the Player back to 9: no luck, dropped the Player back to 8: no luck.
Pulled the revised website and installed the old one: works like a charm.
Checked internet plugins to make sure current player is installed: it is.
!?!?!?! What am I missing?
I am on MacPro, 64 bit. Flash CS5- AS2. Flash Player 10.1 Thanks!
My workaround to upload revised file....
Opened CS5 file and saved back to CS4.
Opened CS4 and saved back to CS3.
Opened CS3 and published file.
Uploaded to server and....All works!
Don't think this is a good answer but it is the one that worked!!!!! Any suggestions?
