Vista 64 reset, losing all my programs and files

[dazsly]

I have just bought vista 64 and installed it with no problems, found all the drivers etc but I turned off vista after installing sdbot and ad aware, I turned off windows defender and reset and found upon starting up again that all my files and settings including mail had dissapeared help! should I format the drive and start again?

Also is ms flight sim x slower and jerky in vista compaired to xp with the new sp1 installed? mine seems 20-30% slower.

Thanks
