@songdogtech great added! but i have tried this solution personally it worked well for me though!

Have you had a chance to activate any payment processor for instance paypal, test payment or anything like that?

try re-uploading all files & folders – except the wp-content folder – from a fresh download of WordPress. Make sure that you delete the old copies of files & folder before uploading the new ones.

be assured to make a back up first

would you mind posting a screenshot that you really renamed the plugins ?

$post_type = get_query_var( 'post_type' );

if ( 'download' == $post_type )
	locate_template( array( 'archive-download.php' ), true );
else
	locate_template( array( 'index.php' ), true );

you need to replace archive-download.php with you archive-download.php whatever the page name is…

i need to see your theme search.php code so that i could assist you better

can you past the code that is already in search.php so i could see & tell you about require changes ?

add this code in search.php

$post_type = get_query_var( 'post_type' );

if ( 'download' == $post_type )
	locate_template( array( 'archive-download.php' ), true );
else
	locate_template( array( 'index.php' ), true );
