So I was trying to install the FFLogs application, and it’s giving me the following error:

> “Sorry, an error has occurred.  
> The application could not be installed because the installer file is damaged. Try obtaining a new installer file from the application author.”

I tried reinstalling Air and redownloading the file, and no luck. Any one else getting this? I see the Warcraft logger is having trouble as well.

Setting my time and date back a year allows me to launch it, but I get this error:

I am able to launch and install it again, though it does still give me the warning.

It’s working for me now, without any kind of date change… Some warnings but installed perfectly.

Thanks !!!
