Strange San Andreas Problem

[glenbo]

ok this is really wierd.

i have been playing it for months,havent installed anything that could of buggerd it up,but as from 2 days ago,i double click my shortcut and nothing happens..same for vice city and same for gta 3.
every other game on my pc works perfect.
i have tried every single crack in gcw database and everyone from ***,and nothing happens.
i reinstall all 3 games about 20 times,got san andreas working once after using the patch fx thing at gcw,but it would not find my saves no matter were tehy were,however as soon as i rebooted..it wouldnt start again.
so again i reinstalled (of course made a entire back up of the install folder,incase the cracks did not work) and still the same stuff,i just double click any of these 3 games exe files,and the xp egg timer pops up for a second,then nothing.

i really dont want to reformat 1tb worth of games,programs etc as it will take me for ever to reinstall everything.

i only use trusted well known programs like alcohol,and all the microsoft proggys like office,auto route and others.

i do a trend micro virus (online) scan every night,also a avg virus scan and nothing.
also i do spyware checks and find nothing using various programs,every other day.
my pc is defragged,up to date drivers.

gta 3 and vice city works with the original disc. san andreas does not.
im still using version 1.0 not 1.1.
the original disc is in pristine condition with no smears,scratchs..and has only ever entered my pc 3 times up until yesterday.

i also emailed the support addy for san andreas 2 days ago.havent recieved a reply as of yet.

what do i do?
the mini image does nothing either.

just to add,i have done about 100 google searchs on ths matter,and i have found atleast 30 people posting on various forums about this problem,and teh best advice i have seen was to run it in 98/me compatiability mode,which for me does nothing.

i also read on a forum that it is some thing that installs with san adreas that kills the game unless you update it.
so ill try that next.

i suppose that is my only option.

since this only happend 2 days ago..
this is what i have installed in the last 2 days.
fahrenheit,dawn of war,toca ace driver 2 uninstall.
no modding or xp skinning ever..and the only other thing i have done accept for playing fahrenheit in the last 2 days is burn off a few back ups with alcohol 120% that i had sitting on my hard drive for months.


EDIT: i updated to 1.01 (tested disc and image) and still getting the same thing.
