Installing FMP 8.5 - won't

[Flanzy]

I was putting data into 8.5 from remote location. No problems in past. 2 days ago lost connection but don't know why. Assume it was power outage but no indication when I go to the host site. But the data base was "damaged" nd needed to be recovered. Figured I'd do that later and attempted to open other data bases, They were also were damaged. For reason I can't recall, I decided to reinstall FM. It says installation successful but no menu to operate from. I threw all the FM data bases away etc and it is still not really installing. Can anyone HELP? I've never heard of this.
