Blank Page after clicking change address

Hi,

I am still getting the blank page after clicking 'change address' button on 1st and 2nd step of checkout. Everything else is working fine. I get the same error even though I switch back to 'classic' template. I have tried to find out the error by 'Debug error tool' (thanks to kobra) and it gives the error as:

[02-Jun-2008 21:05:02] PHP Warning: require(includes/templates/template_default/templates/tpl_checkout_shipping_address_default.php) [<a href='function.require'>function.require</a>]: failed to open stream: No such file or directory in C:\wamp\www\zencart\includes\templates\template_default\common\tpl_main_page.php on line 122
[02-Jun-2008 21:05:02] PHP Fatal error: require() [<a href='function.require'>function.require</a>]: Failed opening required 'includes/templates/template_default/templates/tpl_checkout_shipping_address_default.php' (include_path='.;C:\php5\pear') in C:\wamp\www\zencart\includes\templates\template_default\common\tpl_main_page.php on line 122

There is no tpl_checkout_shipping_address_default.php in the folder. Instead, the file is tpl_checkout_shipping_Default.php. I have also searched for that file in fresh download of zencart but these is no such file. Does the absense of this file causing the problem? How can I get that file?
I haven't made any changes to tpl_main_page.php at all.

Can anybody please help to sort this out?

Thanks.

I looked in a expanded downloaded distribution and this is a file contained with the distribution

If you do not have it or it is corrupt, then this is your issue

Once again Thanks a lot kobra.

You were right. I downloaded zencart again and unzipped on different computer and now I can see that missing file. Probably my download was corrupted. Hopefully this would solve the problem.

Thanks again.
