Microstudio application has stopped working

[zilda]

i have a packard bell tower pc with windows 7 home premium 64 bit operating system, occasionally i find microstudio 4.23 hanging for short periods of time. however it now has started not to open when i click the shortcut icon, to start the programme. When it does open and i click on write a disc i get the message "Microstudio application has stopped working" the only thing i can do is shut the programme down. i also have the full mtu package video hoster - Vogone - keyright - KHPro - songverter and all these progs open and work ok could some one please help as i thought it was the programme so i updated at a cost and it is still the same

yours hopefully Zilda
