How Install Upgrade and How Access Admin

Hello,

In March of this year I submitted an incident for an earlier version of PCMSBuilder and I was supplied with several "test" builds as I worked with the WebAssist staff to address some bugs. The last build installed was "035". However, I was not able at that time to get the system running. I am now at a point where I must get this running.

I have just downloaded CMSBuilder101.mxp and installed this into Dreamweaver 4. I have the following questions:

1) I did not uninstall the previous Dreamweaver extension before installing 1.0.1. Is this OK?
2) In addition to the Dreamweaver extension I also have to get some files installed on the server. The current documentation says that on the 1st use of the Extension (Add Content) that the necessary files are copied to the server. Will these successfully overwrite the "test" build files I had been previously instructed to manually copy to the server when working on the earlier bugs? I would prefer to completely clean up the server; can you tell me what I need to do to "reset" the server back to a "pre-PCMSBullder" state?
3) I cannot locate any documentation on your site explaining how to access the "CMS Admin" facility or the default Login credentials.

Thanks.
