No Longer Available?

I have been dutifully paying my $99 membership fee and submitting apps for more than 5 years. I currently have 6 app's in the app store and have received enough money from my app sales to almost pay for my yearly dues. However, as of today, 4 of my apps are "no longer available", 1 just crashes after opening and 1 "just works."

My account is valid until September of this year. As far as I can tell, my "certificates" have not expired. There is NO information as to "why" this is happening available from the app store. What am I missing?

Please help.
