Nickie, this was all I could come up with--it's from a review of the game:
"The CD even has instructions in case of real frustration. On the PC, use the right mouse button to bring up a small menu. One of the items on the menu is help. The number that you will get refers to a specific hint in a file on the CD. Mainly useful if you simply have no clue what is meant to happen on a screen. Some of the instructions can get quite specific, others are just general hints.
"It is very very frustrating that each screen where you need to find things has a limit of 2 or 3 wrong answers before you must change screens. When you need to test every insect in a garden and you have to leave the garden every couple of minutes, this gets frustrating."
That second paragraph might explain why you can't get anything done. Have you tried leaving the house and coming back in? And you might need to check the hints on the CD.
Good luck.......
