can't access "template_select.php" ?

Hello, first timer here, Zen Cart looks sweet :)

I installed my store and started to config it to my liking, I want to change the template to mach my site look as the store is just another page within it.

I followed the steps in here: http://www.zen-cart.com/forum/faq.php?faq=template_customize

but when I try to click the Edit button inside Admin>Tools>Template Selection the page change to "http://www.mydomain.com/cart/admin/template_select.php"
but I get blank page.

I haven't edited any files yet beside removing some demo categories from the Admin section.

Does anyone have an idea what could that be?
any input is appreciated :)

could be the dreaded FTP black hole or a bad configure file. Take a look at the things template_select needs to operate and see if any are missing or not set correctly.

Thank u dbltoe, I'll try reinstalling from the begining...

Could be an improperly-formatted "template_info.php" file in a custom template folder...

thx DrByte,
I ended up reinstalling the whole thing.
now works fine with my custom template.
