Flash keeps crashing when generating +5Mb SWF files that previously worked

Hi all,
This is driving me crazy, I tried looking into Adobe FAQs and other places inside the site but cant find a good solution to this, in fact I found people asking the same issue. The fact is Im making a game that after being published is 7Mb SWF, this was working great and in fact I havent made any critical change there, only updated a text field with a typo (no code), then when I tried to publish it crashed (other big games I made are making Flash crash too), and crashes the same when hitting ALT+ENTER or just selecting File>>Publish or File>>Publish settings>>Publish, I reinstalled the whole CS4 3 or 4 times and even got a tool from Adobe to uninstall the player (I thought it uninstalled the player used from IDE but its apparently the other) asuming the issue could be there but still keeps crashing after I re-install it, oddly small FLA files can be published, I looked into CS5 faqs and they said they can set the cache size there but I cant find in CS4, and Im unsure if is due to that but just my guess after all I read about this, could someone help me please? Thanks a lot beforehand, I have been fighting this for 3 days almost sleepless
