amember remote installation

I have recently purchased amember remote script.
As per the steps, I have downloaded API module and activated everything. I got the REST API Permission key for amember remote and have setup permissions correctly.

I have downloaded the amember remote scripts and copied the scripts (from inside amemer_remote folder) to a new folder called amember-remote on my remote webserver (runs on apache2 php server).
So the folder structure is like www.mywebsite.com/amember-remote

However, I am having lot of issues.

1. I am getting Not Found error when trying to access www.mywebsite.com/amember-remote/admin
2. When I access www.mywebsite.com/amember-remote , it prompts me to enter username and password. I entered default username/password (admin/123456) and got error message "Could not read config.php file, please contact administrator to fix it"
3. Then I found that there is no config.php script inside amember-remote folder, so I renamed config-dist.php file to config.php file. Tried accessing /amember-remote/admin couldn't. Tried /amember-remote with default username and password and stays on the same screen and nothing happens.
4. After that I tried to manually edit config.php file by putting rootUrl and API key and then tried login using default login details and says "username and password is incorrect". Tried one of the user from my amember database and got error "Internal Error - could not write file".

Can please anyone help? I am not sure whether I have to change anything inside .htaccess files which I got when I downloaded amember-remote scripts?

How can I access amember-remote/admin area so that I can change the default login details and how can I configure which folder I want to protect?

Ok. I have just created the ticket. Ref no : BVR-97342-557
