System error encountered in AdvanceBox Turbo Flasher or ATF

Hi,
I am using Advancebox Turbo Flasher (ATF) for Nokia Services. When I opened ATF, I got a System Error message code 5 and Access was Denied.
I tried uninstalling and installing ATF and I still encounter the same problem.
I think the problem exists somewhere else and not with ATF. I might be wrong.
I have a problem with Advance Turbo Flasher When I connect ATF and click on the icon the following error is displayed. I am a user of Windows XP and please help me to resolve this problem. The error is given below. Thanks.
Please provide step by step procedure.
Thanks.
Error message displayed:

AdvanceBox Turbo Flasher
System Error. Code:5
Access is denied.
