Some things to think about..

How important is the information in the folder to you.
  • is there unique data there or just stuff you downloaded
  • how hard would it be to just re-make the unique data
  • how much time and money would you spend to recover the data


Also exactly what version of Winguard Pro 2005 is it (5.7.3.1 or 5.8 or 5.9.6 or something)..
What version of windows are you running (XP or 98 or something)..

You could try and contact the manuefacturer..
