several programs will no longer open

i have just recieved an old(i think its a mid 2004) mac ibook g4 for a graduation gift

several programs will no longer open

google skechup
itunes
yasu
the icons will bounce in the dock then disappear
i have tried clearing out my cache with tigercache cleaner and reinstalling these programs
can anyone help me

also i am now having trouble installing the new flash update the installer just exits when i try to run it

Do you have the install discs? I would start by running disk utility and repairing permissions. You could verify the disk at the same time, just to see what it shows up.

the things did not come with install disks also i have tried repairing disc permissions
if you mean the mac osx install disc no i bought this mac second-hand
if you have anymore ideas it would seriously help

Ok, you're a little stuck without OS install discs, but you could try running fsck to see if it finds any issues it can fix.
Read through my advice in the following thread to see how to do it.

is there anyway i can get a copy of the reinstall disc because i have tried everything you said and it hasn't worked
and how much is a new copy?

You could get a generic version of Panther or Jaguar on eBay for little cash, probably £10-20, which would be ideal for your machine, or you may find the specific discs for sale if your lucky. Tiger would be a step too far I feel.

is there any way to revert my os to the way it was a couple weeks ago

Not unless you happened to be using Time Machine and the last back up was then. Sorry!
