When I install DarkPhysics for DBPro I always install 08 first then 09, I believe Dark Dame Studio was updated in 2010, and that may be the updated date, I believe Dark Game Studio was updated every 2 years since 2008 I believe is when it was launched, I am still reading issue 37 of the Newsletters, got 59 more to catch up where I started in 2010 ^^...
But Anyway, yeah Use 08 then 09 and I too have the same files...
I identified them as release dates as I am quite familiar with dates in pretty much any sequence...
For the UK the most common [And remember TGC is UK based] DD/MM/YY
Typically you have DD/MM/YYYY or simply DD/MM/YY
Alternatively in some countries you have MM/DD/YY
sometimes the year comes first YY/MM/DD
So as a '/' is not a good idea or even possible usually in file names, XXXXXX or XX-XX-XX in digits would usually indicate a date
Hope that helps
