SearchForm.html.sbk? Missing SearchForm.html

[enigma]

Windows XP w/ SP2
Sugar Suite Version 5.0.0b (Build 3150)
Webserver Apache HTTP Server Version 2.2
PHP Version 5.2.1
MySQL server version 5.0.33


Problem: I would like to modify the SearchForm.html file of the Accounts module but the file doesn't exist. I only found SearchForm.html.sbk and SearchForm.html.bak at this location:

crm/modules/Accounts

I tried to rename each to SearchForm.html and was able to apply the modification I want but I got this warning just below the Accounts Home label:

Warning: array_merge() [function.array-merge]: Argument #2 is not an array in D:\xampp\htdocs\crm\include\utils\array_utils.php on line 77

Warning: Invalid argument supplied for foreach() in D:\xampp\htdocs\crm\modules\DynamicFields\templates\Fields\TemplateRadioEnum.php on line 90

I undo the rename command and checked out other directories for similar file which I found two of them at the following address paths:

crm/custom/modules/Accounts/SearchForm.html
crm/custom/working/modules/Accounts/SearchForm.html

but changing any of these files doesn't apply the modifications i want to achieve.

How can I restore SearchForm.html at crm/modules/Accounts?
