I bought uniblue registry and run it a couple of time ,ok,third time they put up a quick note saying that once they cleaned it might change ,as before it automatically backed up,but thye third time it warned me i checked it but it said that i could not back this one up ,i thought it odd but off it's own back went on to clean something like 143 errors,lo and behold after it i lostmy access to the internet ,rang my IP provider BT and they said 'after trying and checking they seemed to know and said there was nothing they could do but that i shouod not allow anyone other than them to control my wireless and that was it ,i system restored but every time a page came up it was snatched away .I three or four times had my computer telling me there was noything wrong and i could read for myself ,but still when i brough up a page my adapter would be taken over and no access and i got someone in who said that it needed to be reformatted something about the numbers and left .since then i think windows have downloaded a file with file sharing in it sort to try and help ,as i am disabled with a head injury and i get so bloody confused and may have made things worse ,i think i may have to reinstall my whole system . any ideas anyone please ,as i rely on my computers especially myy xp as i have a vista now but this computer i cant carry so and help please
