And recommend that if taking a trial/error approach to first use a non-permanent designation such as a 302 until sure that it works as intended. Especially with various cache capability between the site and the customer. Once the rewrite works, then go ahead and make it a 301.
I agree with simon1066's suggestion of at least enabling the RewriteEngine. The line above it may not be supported by the host, but is intended to provide a little bit of navigation protection.
To address the requested rewrite, the .htaccess file would need to be at or above the directory to which the domain name is located. By above I mean that the file path would be "shorter". This way when the domain is asked to find /align, that it will start at the domain name. If it were placed in the store directory, then it wouldn't be found if first the domain name were sought/used.
There may be some modifications necessary as can be identified by your host to ensure that the correct format is used for the environment in use.
