Sorry second part, I brought a new internal hard drive for my desktop computer had Tekserve here in New York City install the hard drive in my Intel Mac IMac computer. Reloaded all of my Premium CS4 creative suite software into this new hard drive all with all of my other software fresh from the cd rons. I was also told about 6 months back that there may have been a problem with my internal computer's hard drive. So everything is fresh and I'm still having this same code error 5 and having Indesign CS4 tell me once again that my book file has a code error 5 happens. Adobe Indesign technicians tell me once this code error 5 happens the files are corrupted and can not be open again. So all this happen again using Idesign CS4 taking all of the steps above..
