Just as a follow up.
I went into SSMS and then analysis services.
I right clicked on the cube and went to browse. There was an error. I then right clicked and clicked on process. Once it finished processing, I was able to see the cube in excel.
So I learnt a little something of troubleshooting of Analysis services via SSMS.

Things will work out. Get back up, change some parameters and recode.
