ipod touch stuck in restore, wont restore!!!

+(I will give 2 months of IT help [windows/networks] if you solve this, 1 month if you help me- Im a IT Tech with a degree. - see profile)+

*I was trying to sync my iTouch and it blipped and everything was gone.*
*Now it is in Restore mode permanantly. When I attach it to iTunes, it recognizes iPod in Restore mode, but:*

1) If I try to use the original ( 1.7.7 ) ispw to restore ( with shift/restore), it fails at *Preparing iPod for Restore* and says *iPod can not be restored. Error [various]*

2) If I try to restore to the new (3.0) ispw it fails with *Network Time Out*

3) If I try to use the 3.0 which I have already downloaded ( with shift/restore) another error #1431 occurs during restore.

4) I can not update to iTunes 8.2 as when I try it gets to the end and then says that it can not access the registry key for 'itpc' or similar due to permissions, when I open regedit to look at these keys I also get an error saying that I cannot access the keys due to permissions. I have tried opening in admin account and still "permissions not allowed", I have tried running iTunes though admin, still the same. I also can not alter the permissions even when I am at the highest permission level.

It isnt even seen by iTunes unless I enter DAC mode. Then it askes to restore it but fails every time!

+The USB has no faults showing and I updated all of them to be sure.+
+Everything was fine before this. Running firmware 2.0 or 2.2 ( cant remember or access it ).+
+I dont want to delete the iTunes as Im worried it wont be able to install again and I will lose everything. ( and thats ALOT!)+

+I REALLY need my iPod.+ I use it for work, +I work with disabled children as my 'real job'. IT is just extra $. _All my contacts, emailing etc is trapped now in a iTunes that just refuses to work_.+
As this is SO important to me and the children I work with I am offering:
