Created Unassigned: Provisioning User Profile Service Application Fails [19720]

Hello i m trying autospinstaller for the first time, although i been "messing" with SharePoint for a while i consider my self a little green to this environment when comes to power shell + SP. So i decided to give autospinstaller an try and learn a bit as well. Okay .. so the problem i m having (or the error i m getting) is this:

```

I did an small google Search and i found an [similar issue](https://autospinstaller.codeplex.com/discussions/284432), but in this post the people there said you need to have at least 2 web application (1 Portal and 1 MySitesHost) , however i had 2 already had them in the setup 1 in port 80 witch is the Portal page (template SPSPORTAL#0) and the other one is hosted in port 81 witch is the My Sites Host (template SPSMSITEHOST#0). i m using AutoSpInstallerGUI as an tool to setup the XML file, if anyone could help me understand why this is happening i will appreciate it.
