Hello, for the people who say the client does not work, make sure the version has no custom value. Last client people said to use a custom version to fix the client. Since it's been updated it's possible the custom version ported over to the new swf file. Even if the custom version is set to x34.1.0, it still will give you infinite load. Don't use custom version at all.
If you don't know how to change the custom version then you probably never set it yourself so this won't be the solution to your issue.
