Microstudio will not start

[Ramblin]

I have had Microstudio installed for some time and when I downloaded it I saved it to CD ROM. A couple weeks ago I had a problem with my computer and had to use my recover disk. This messed with several programs including Microstudio. When I click on the icon, it does nothing. I have tried right clicking and going to open, rebooting, reinstalling, ect. But I have no luck. When I use the disk to try to reinstall it, it says it cannot find the link to it on the disk. It says it is missing. If I download the newer version, will this solve the problem? I don't want to just download it and still not be able to use it. Thanks.
