Insert your original installation disk, as it won't let you import files without it.
In the 2600V, click on the `Import' tab next to the window. Tell it where the files are on your hard drive. I can't remember exactly how it shows on screen, but it should be clear when you get to that point. I think you just click on the name of the bank you want to import.
It may not be obvious that they've imported. After clicking on the bank, have a look on the menu of banks and you should find the new bank(s) listed.
If you have any problems, post here again and I'll check through the process myself to see if I can see where the problem is.
