Hosster crashed while editing song

[xxyzz]

When editing my songs, Hoster crashed. It will not restart. Clicking on the program brings up the hour glass but nothing happens. I have tried reinstalling the program without first uninstalling. Then I tried a system restore to a earlier point to where I know Hoster was working. I then tried uninstalling and reinstalling. I then went into msconfig and disabled all start up items. None of these fixed the problem.

I have a brand new Dell laptop with no other programs installed.
Intel i7-3630QM 2.40GHz 8 gb ram 64 bit Windows 7
1 TB hard drive, 1gb NVIDIA GeForge GT 650M
Hoster 508.11

Just on another note I was previously running this same version on a previously owned Dell Laptop pretty much the same as I have now but more power on this one than the previous one. Have been using Hoster for numerous years so I am pretty puzzled why this happened. Short of reformatting my computer I don't know what else to try.
