I currently ran into some trouble with my Mac G4. I actually was having a few problems with one of my installed production programs that i create music in (Propellerhead Reason 4.0) and it actually stopped working. I tried reinstalled the program several times and ran into the error ( error -31) cannot read/ write files on disk when i initially installed it on this computer months ago. I not sure if its due to new programs and updates ive put on my computer or what so i figured it was and decided to boot into mac Classic os 9. BAD IDEA..Now the stupid thing wont boot up period...so not only am i having problems with my music program now my computer is jacked up completely. When i try to boot up i get a blinking floppy disk with a question mark on it ..GRRRRRRR....and the computer was a gift from a family member so i dont have the INITIAL os disk it needs. However i do have OS tiger on disk and OS panther. I tried the whole boot then press C to resinstall...NOT WORKING!!..and i also try wipe drive to wipe it clean...didnt work...its like the press anf hold C option is not working all together...i even tried reconfigured the jumper settings on my hard drive..NO LUCK!....CAN SOMEBODY PLEASE PLEASE PLEASE HELP ME IF YOU HAVE ANY ADVICE AND ARE AN EXPERT WITH MACS IT WOULD BE GREATLY APPREICIATED...THANKYOU....
