Won't let me log back in?

Ok so for my site http://www.countrysweets.net I have set up a zencart store located at http://www.countrysweets.net/index.php

When I make an account I can make one purchase but then once I log out I can't log back in? I have check in the admin tool for zen cart and the account is still there, and hasn't been deleted why can't you log back in?

Also one more question. If i set up a pay pal express check out will the option to check out with the use of pay pal with out clicking on the specific pay pal check out, like the regular one ,if you look at my site and pretend to but something you will see it has a regular checkout and then a pay pal express one, and choose to use the pay pal and not go to the pay pal website will i still get the money? or will it be lost in cyber space?? And yes i did set up pay pay express account.

I got
"There was a security error when trying to login."

Try switching to the classic template to see if this still happens

On pay pal express check out - You should only have one PP method active remove any not wanted
admin > modules > payment

Ok i tested that and it does work on the classic template. What do i need to do in order to fix it for my custom one?

Check for custom files in your template that will be located in these locations

includes/templates/12541//templates/tpl_login_default.php
includes/templates/12541//templates/tpl_timeout_default.php

If you find that you have them add the statement outlined in the tutorial using a plain text code editor, save and replace them
