Conversion Software

Help!!!

I need to be able to convert advantage database files (.adt) to .csv files. I have looked for an application that will do this, but the only thing I have found that will read the .adt files is ABC Amber Advantage and I can only find the trial version of it. The company is out of business so I haven't been able to buy the program anywhere. If anyone knows of software that will convert .adt files, or of a way I can get a hold of the full version of Amber Advantage, the information would be greatly appreciated.
