Microstudio

[Karaokeman41]

Started with Microstudio V3.0.0.0. Upgraded and installed 3.0.0.1, then 3.0.0.2. Now, all of a sudden, for reasons unknown to me, Microstudio V3.0.0.2 would not work.
Microstudio interface never appears on computer screen but Task Mgr. shows microstudio.exe which I eventually have to "End Process".
I uninstalled all completely, manually cleaned out Registry (using Registry Find), did hard drive search and manually deleted Files/Folders related to Microstudio; and then reinstalled starting with V3.0.0.2. Same problem.

I Uninstalled V3.0.0.2; manually cleaned out registry; did hard drive search and manually deleted Files/Folders related to Microstudio;and reinstalled starting with V3.0.0.0. Same problem. Microstudio interface never appears on computer screen, but Task Mgr. shows microstudio.exe.
I have not changed computers. Still using same Laptop. I also notice from Forum, Microstudio V3.0.0.3 is now available. How do I obtain?

Suggestions? Thanks
