Sorry you're still having problems! The message indicates that your Admin pages are where they should be, but your WA_Globals files aren't.
Now that you know about the .htaccess file requirements, It might be easiest if you just remove everything from the remote server (apart from your .htaccess file) and upload the contents of a fresh copy of your PowerStore folder to the root directory of your site again.
You were almost there last time, so now that you have the PHP5 issue resolved, you should be able to finish the install and hopefully all will be fine.
I attach a zipped .htaccess file in case you had problems with that aspect. Unzip it and include it in the files and folders being uploaded to your remote server root directory if you need to.
