Re-upgrading Hoster v4.08...frustrations

[bendrew]

It just happened that I removed some programs that i don't used everything is fine. All programs, even microstudio and songverter is working when i happened to open Hosterv4.08 and computer says "it encounter an error and it will closed". So, tried to re-upgrade hoster and upon reaching the submission of data to MTU, It says " Your Registration Code was found disabled.The installation program was closed and your internet Browser is now showing an instruction page at so and so................... Then I submitted an issue to MTU support for almost 2 weeks now and i'm still nowhere to go. I tried again to install hoster and the same message. This is too much frustration already on my part..That's the reason I post this problem of mine. Any suggestions.......
