backed up to PHP 5.2.6...only phpinfo.php works...help!

retreated to 5.2.6...phpinfo.php works
cannot connect to SQL Server 2008 (once worked for months)
doc_root =
cgi.force_redirect = 0 (recommended turned off for IIS)
extension_dir = "C:\PHP\ext"
I uncommented ALL the extensions like:
extension=php_mssql.dll

IIS 5.1 properties->home directory->configuration-> .php php5isapi.dll

I removed cgi 1.5 (trying to return to the state where everything worked)

My easy standalone (below) also quit working when I select demo

I get:
