Just had to replace my hardrive lost everything.
So whenever i upgraded lightroom my catalogue automatically installed then i would uninstall previous version.

So I've installed it but I'm not sure how to inport all my previous lightroom catalogue's which i backed up on a seperate drive can any one help?

File, Open Catalog (or Ctrl O, whilst in the Library module) then point it to where the catalog is.
