Carrara P 8.5 64 Install

DabblingDan

I am all screwed up and hope some of you knowledable folks can help point in the right direction. I used the Install Manager to dowload and install the upgrade and associated content. Went verfy smoothly. Unfortunately I don't know where it went! I open the new version and there is none of the usual content (scenes, objects, etc.). I can not locate M5 or V5 or the default items provided with them.
Can someone give me an idea how to straighten out the mess I have gotten myself into?
I am using Windows 7 and appear to have multiple folders in Documents\DAZ3D - previous installs of version 8 and 85 beta.
I will appreciate any guidance you can provide towards getting all my ducks in the proper rows and having previously installed scene and objects that come with Carrara as well as other content I have picked up over the years show up in the proper tabs in Carrara.
Thanks in advance
