my flash site wont play anymore

hello,

im using windows 7 and the latest Mozilla browser. When trying to view an old flash site of mine which used to work properly last time i checked, i get the message that i need to update my flash player..i already did that, but it still won't play.. funny thing is, that there are actually 2 sites under one url,and one of them works fine..this is the link

http://dromon-ate.com/

it is in greek..so the link on the left, opens the first part which works fine, though the one on the right gives me the error message

a)

b)

those two sites were build around the same time on the same platform and flash and used to work properly...what's wrong?

thank you in advance!!
