Panel tells me to download upgrade

Hi, I am trying to use the free demo version of flasheff2 to see if it's worth the buy.
Sadly, after installing it, the flasheff2 panel always tells me to download the newest version, wich I just did.
I already had some problem installing it since I am using an english version of flash but I used to use a french one so the files kept going to the fr folder.
I use flash cs4 on a mac.
Please help me out, the promotion ends today and I need to test it before buying.
Thank you!

Go to [www.flasheff.com] and download the free version.
After you have download it, unzip the files and install the mxp. After that restart flash and the update is complete.
