Open older file format.

[hlinden]

How do I open my older design files saved with the file extension .PRO. I am unfortunately not sure of what version I was using in 2009 and 2010 but have unsuccessfully tried several older Windows versions such as 2.4, 1.8, and 1.6 all of which fails to recognize my work files. I am currently using SH3D 3.2 on Windows 7 that besides the inability to load my older files works as advertised.

Please help.

Sweet Home 3D files extension have always been .SH3D.
You must have created your .PRO file with an other application.
