Well, it sounds like things just didn't get completed properly on the installation so you are getting a cascading series of errors.
Since this is a new, fresh install for you, try this.
First of all, be sure that you have installed the program into c:\donor5 (not c:\program files\donor manager ... or anything under "program files.")
Second, go to the folder c:\donor5 and rename the data folder to something else, like c:\donor5\data_bad
Next, restart the Donor Manager. It should ask you for name and address info.
Once you get to the screen that has a button "start using the donor manager" ... click that button.
If you get errors after this point, let me know.
And, please feel free to contact me by email at
john@donormanager.com. If need be, we can schedule a remote support session and I can actually see what you see and can troubleshoot live on your computer.
