OS crashed and lost everything

…i just booted back up with windows 7 and i got all my drivers back up. but i don’t have my cubase le 4 installation disk. if i download just the updated drivers will that work? how am i supposed to do this? i hope someone can help me out.
i got cubase with my presonus firestudio project but i misplaced the cubase disk

No that won’t work.

You would need an original installation of LE4 to apply the updates too.

Maybe asking Steinberg or Presonus nicely for a new install disk.
