Missing font in the template psd

I am on photoshop CC 2014. I need to modify a wedding invitation card. When I opened it I get this error Missing Font.I try to resolve this problem by choosing the proposed font as mentioned in the images below. After that, I need to write some text in arabic language but I remark that the direction of paragraph is inverted (from left to write) and the icon is not shown to change it. How can I fix this problem? The problem is created just when I use this template (I mena when I write on new text, it works fine). How can I fix it? thanks
