** Applications not launching ** HELP

[jordanborth]

Ok, so, after I had downloaded Safari 3 beta, my MSN kept screwing up and randomly quiting. I used the uninstall package that comes along with Safari Beta 3 and rolled back to Safari 2. I re-booted and went to open up iTunes. The app. bounced once in the dock... that was it. The program didn't open, nothing happened. I tried opening MSN and Safari 2 and the same thing happened. I then tried some others and got mixed results: Limewire opened fine, App Zapper did not. iPhoto, iCal, pages and firefox all work, sofware update in system preferences does not... Can someone PLEASE help me??

** Update **
Tried my dashboard... Nothing comes up either... The screen dims, but no widgets come up... I also tried re-installing iTunes, but when I clicked on the itunes.mpkg, it just 'flashed' and nothing happened...

Can you open disk utility, if you can then repair permissions, otherwise boot from your CD and run disk utility from their to do it.

I can run disk utility and have done so a couple of times now hoping that it would solve the problem but it hasn't... Any other advice?

 

[0007776]

I can't think of anything else besides backing up what you need and reinstalling the OS, but I would wait a little while to see if anyone else has other ideas.

Ok, I'll get it all ready. Do you have any good solutions/programs that I should use to back up my data? Would something like Toast Titanium work well? Drag everything that I would like to back up into it and make DVD's? thanks a lot for the info

same happened to me. use disk utility from the install disk and repair disk and permissions.

 

[jordanborth]

Ok, so run it from the install disk, not my computer?

Insert the install disk, and boot from it, then run disk utility from it.

I would also do a fsck...

 

[jordanborth]

Could you kindly let me know what an fsck is?

Could you kindly let me know what an fsck is?

http://en.wikipedia.org/wiki/Fsck

The system utility fsck (for "file system check" or "file system consistency check") is a tool for checking the consistency of a file system in the Unix system and clones thereof.

**Update**
I have backed up all of my important stuff, but unfortunately could not find my installation disks... I have no idea where they could be. Anyways, I borrowed a friends copy and when I try and boot into it, it says that it can not be installed on my computer... I thought it may have been his copy, so I tried another copy... Nothing. So what am I supposed to do? I can't boot from the disk as it won't allow me too.... Help?

OOH, I know... I think

anyways, i'm having the same problem i just googled to see if anyone else had an answer. anyways, i hope you didn't reinstall the disc because this person seems to have the solution:

but i can't figure out how he downloaded the webkit from the webkit website (which i found via google):

http://webkit.org/

if anyone can direct us to a download site with mirrors or something, or explain to me what the nightly build thing means (does it only work at night?)(I'm a bit of a newbie)

thanks
