PHP/HTML Glitch help

[imtuned]

Alright, so I am coding a music membership site and everything is well but when I log in, the DIVs I have placed goes all over. Here photos and the code for that section, they will better explain it:

Before logging in(Correct layout): http://i39.tinypic.com/1rce2c.png
After logging in(Messy layout): http://i43.tinypic.com/1z4e5cj.png
Here got my coding: http://pastebin.com/43B7ymt3

I'm hoping somebody can help me out with fixing this glitch, I've tried everything!

The screenshots are useful, but we could use a link to a live page. Also, the sample code should be minimized. The PHP code is extraneous; all that matters is the HTML and CSS.

Don't use tables for layout. HTML isn't a formatting language, it's a document structuring language. Use markup that's more semantically appropriate, such as paragraph or list elements, then set the layout using only CSS in external style sheets (not inline).

I did what you said about the tables and layout. That fixed my problem! I guess it was the tables, I'll make sure I don't use them anymore.

Thank you very much!
