HI! I have an equipament that is called FinalScratch(www.finalscratch.com) and it allows me to play my mp3 files using my turntables. I will explain the procedures I went through to install: 1) I installed the software. 2)I reboot the computer. 3)Connected the USB cable and waited for the recoginition. 4)reboot my computer. 5)I ran the software(FinalScratch Tracktor). I tested the softwre and it was working fine but once I shutdown the computer and turn it on again(another day for example or only if you reboot the computer) it didnt work anymore. I've sent an email for the support of this product and they've sent me an explanation saying that I'd have to follow this steps to fix the problem: Desinstall TRAKTOR FS via the \'Software\' Tool in the Windows Control Panel. - Plug the ScratchAmp into your computer and delete the ScratchAmp A and ScratchAmp B drivers from the Windows Device Manager (\'My Computer\' -> \'Manage\' -> \'Device Manager\' -> Audio, Video, Game Controllers). - Install the newest USB patch (#822603) from the Microsoft website, located at: http://support.microsoft.com/default.aspx?...kb;en-us;822603 - Reboot your computer (ScratchAmp not plugged in) - Install TRAKTOR FS and the ScratchAmp driver (still without ScratchAmp) - Reboot your computer (still without ScratchAmp) - Now plug in the ScratchAmp without going over a USB hub and preferably to another USB port than the one previously causing problems please also make shure that it was without any energie 1 min. before. - After the recognition of the hardware by the operating system go to the USB Controller section of the Device Manager (\'My Computer\' -> \'Manage\' -> \'Device Manager\' -> USB Controller) - Two of the listed (Host) controllers are responsible for the ScratchAmp. In the \'Advanced\' tab of their properties you find a checkbox to suppress USB error messages. Please check this box and repeat this operation for the other available USB (Host) controllers. - After this reboot the computer with the ScratchAmp connected please notice that it s strongley recommendet to install also servicepack 1 for win xp Now, I have windows xp sp2 so I dont have to update the USB drivers.I do all the other steps. After I do this it works fine but after about 40 minutes my computer stars to get very slow.IF I hit ctrl alt del the cpu percentage is at 100% and if I change folder inside the software it freezes and I have to reboot my notebook.Imagina I am playing in a club and I have to reboot my notebook? My question is:Please Help me solve this problems.The one avoiding the work of having to reinstall the software everytime I want to use this equipament and the other one of freezing when I use it. thank you very much!
