LMAO! Are you sure you aren't me? Everything you just said is the same on my end. I have about 987 MB left of HD space....never defrag...and am always juggling things for space. LOL! Again...my hubbies says that your PC meets all the requirements for running this program. He says you may have either a bad copy of the Demo....or some software conflict going on somewhere. Just out of curiosity he asks if you are running Win98 or Win98SE. He says that Win98 had some bugs that cause software conflicts and that's why they released the Second Edition, Win98SE.
