Does your new computer have different drive letters? Delete the file ADSPROF.xxx (where xxx is your data selector) from your data directory. The next time you launch Adagio, you will be asked for the location of your currency and task files. Perhaps they moved when you set up the new computer.

You should also run the program CHKSYS.EXE from the \softrak\system directory to make sure that everything else is set up correctly on your new machine.
