Address book problem in Email

When using the email program, if I write a new message, then click on the "To" link, or address book I get the following error.

html/english/calendar/calbook.html is not readable, please check file permission!

I can get my address I need by just typing it in, but clearly something is wrong.  How can I fix this?

Thanks!

I'm guessing there is no quick fix for this?

nope. we're going to upgrade to the latest version of the software in a few months though. 

@erik, your favorite browser google chrome does not open chess.com emails. When i try, it asks me to download the php. Hope with the new software, this problem will be sorted out (or do i need an addon for chrome to open chess.com emails?)

OK thanks for the reply erik
