I had to re-instal my operating software a few months back and have not used i Finish since. I installed the software (4.6) with no issues on my xp machine. (this software has worked on this computer in the past) The install gave no error messages or any indcation of problems. When I restarted and tried to launch iFinish, the Media 100 splash screen came up and it seemed to be launching but after about 20 seconds, the splash screen went away and the program never started. I have tried re-booting and also an uninstal and re-install.
