Hey guys long time no talk

My old Blender 2.44 I think recently went wonky. I'm assuming it was a video driver issue. My click select function no longer selected at the position I was clicking.
I'd made a lot of updates to drivers for Brink and then Rage that I didn't really want to change so I thought it was time to update Blender.
Now before Blender allowed me to have multiple copies. This time it has overwritten my old Blender.
I don't mind learning the new UI and procedures for work I used to know how to do. It all seems a step forward in many ways.
My problem is not being able to find an ase import/export script....or if I have a script that works (which is possible as I've been trying a few), I don't know where to put it and how to access it in blender.
My Blender directory is a bit of a mess as it still has old 2.44 folders in it.
I installed the new python and set the runtime variables, which it seems I didn't need to do.
Any advice on which scripts to use and what to do to get the scripts working?
I have a project in my head that I really can't face creating in GTKr, but without ase support in Blender I'm a bit stuck.
Thanks as always.
A
