Ical, Adress Book and email information lost!

since you have time machine backups you can easily restore all that data from TM. but before we get to that please clarify what exactly happened. do you have ANY of your personal info left in your home directory? any documents in the Documents folder, movies in the Movies folder, music in the Music folder? is any of this stuff still there?
do you have Guest account enabled on your computer and have you used it recently?

Hi,
thank you for trying to help me. Let me answer your questions: So all my personal information is still there movies, pictures, documents and others. I don't have an guest account.
There was some message from my keychain, but unfortunately I don't remember it. Something else, my skype behave strange. I had some credit in it, but now it shows me that I don't have any. When I open it in the web, I can see this credit.
I installed sophos antivirus programm and it detect just some troj called Troj/BytVrfy-C.

never heard about Troj/BytVrfy-C but info on the sophos page suggests that this is a windows trojan. it can only affect windows. are you running windows?

I don't think that this is the reason, but I actually don't know.
The changes started also with change of my desktop picture, and reset all the system preferences.
My all programs are also there.
As I did my back up, I excluded the applications from it, will this be an problem?

that prevents you from doing a full system restore which would have been the safest thing here. this is why I recommend not excluding any system files or applications from backups.

so in your situation I would suggest the following. go to system preferences->accounts and make a new admin user. log out of your current user and log into the new admin user. open /Users folder in finder. inside are the home directories for all users on your computer. enter TM interface and scroll back in time to a point before all the problems started. select the home directory of your main user and hit "restore". you'll need to enter your admin password. in the popup asking you if you want to replace the original or keep both choose "replace". this will restore the entire home directory of your main user. log out of the temp admin user and log into the main user. all your stuff should be back. when you start Mail it will say that it needs to import your mail. say "yes".

So far that is the information I can give.

Thank you very much one more time

this is strange. in this case instead of restoring the whole home folder restore just the Library folder in it. that might be enough. then try logging in as the old user.

also, run "verify disk" in disk utility. if it reports any errors boot from the snow leopard DVD and repair disk using disk utility there.

you are welcome!

but please run "verify disk" in disk utility. you should make sure that there is no file system damage that needs to be fixed.

Oh, there is some problem. I will try to fix it. Should I just reinstall the Snow Leopard?

that need not be necessary. boot from the snow leopard install DVD, start disk utility from the utilities menu and run "repair disk" on the main drive. see if it can fix the errors.

to boot from the DVD, insert it, reboot and hold "c" at the chime.
