I found a little glitch with the Ultimate Deer Data disc yesterday and thought I'd share the solution. I found that the Deer Recognition tests wouldn't open - they looked like they were about to and then nothing happened. I solved this by running the main program as an administrator.
1. Open My Computer
2. Right-Click on the CD/DVD drive with the disc in it and click on Open
3. Find the file called BDS or BDS.EXE, right-click on this and choose "Run as Administrator"
4. You should now be able to open the Deer Recognition tests
Hope it helps some folks
