Fix htaccess redirects

Need this fixed quickly. If anyone has knowledge and can help, let me know.
------
I am moving my store back from Shopify. I am trying to redirect all products from their shopify paths:
mydomainname.com/products/productnamehere
to the new path on opencart
mydomainname.com/productnamehere

My htaccess redirect looks like as follows:

RewriteRule ^products/$ http://www.mydomainname.com/ [R=301,L]


RewriteRule ^sitemap.xml$ index.php?route=extension/feed/google_sitemap [L]
RewriteRule ^googlebase.xml$ index.php?route=extension/feed/google_base [L]
RewriteRule ^system/download/(.*) index.php?route=error/not_found [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !.*\.(ico|gif|jpg|jpeg|png|js|css)
RewriteRule ^([^?]*) index.php?_route_=$1 [L,QSA]

The url will come out as:

h--p://mydomainname.com/productnamehere?_route_=products/productnamehere

Does anyone have any clue how to fix this? I have just moved and don't want to be penalized for all the page errors.

I have tried everything on this page to no avail: http://forum.opencart.com/viewtopic.php?t=138549
