This is not affecting all users, but some users have reported that on their Mac OS X machine using the Safari browser they are having trouble loading the SendOutCards Flash Card Editor. We have not yet narrowed down which versions of the browser specifically are having problems. One suggestion is to try and update Flash on your computer by going to https://get.adobe.com/flashplayer/
from Safari. Once the flash player is updated make sure to turn off Safari (Command Q) and restart it. If that does not correct the problem, for the time being please try another browser like Chrome or Firefox. We will continue to research what changed with Safari and/or Flash and try to resolve this problem.
