Can't access pix in Samsung A900

Last night I went to show a friend some pix I had in my phone, and when I clicked on My Albums it just gave this message: System busy, please try again later. Wha???

I made a call to test, so the phone was working. It is charged up. I deleted some text messages so it should have room.

It is the same today. I read through the whole lousy manual and found no mention of such an error message. Searching in this forum hasn't turned up anything, nor has searching on the various Samsung/Sprint support sites.

It does not seem unreasonable to me that error messages would be listed somewhere, but if that is the case I have been unable to find where.

I sure hope someone can help me! Thank you.
