Autosketch 9 - Unknown file type

[a_c_hannon]

On my desktop PC Autosketch 9 cannot open any previously saved file - it says "Unknown file type".

If I create a simple test drawing, save it, close it, then I get "Unknown file type".

And yet Autosketch 9 still works fine on my laptop.

What has gone wrong?

The 'unknown file type' problem seems to be solved by Removing Autosketch9 (from Control Panel), and then re-installing Autosketch from the CD.

Perhaps the problem is caused by something getting corrupted?

If it happens again can you try this - Delete file type association in Windows, reboot, then re-associate file type
