I work on some catalog in adobe illustrator cs. I can open them and edit them but when I want to save them it won't let me.Tells me that the file is open or used so I have to save it as a new file.example:file catalog1.ai opened the edited the trying to save and won't let me so save as catalog2.ai.Then catalog1.ai is what gets the problem when I try to rease it cause I won't need it.Then tells me also file is open or used by another person and it keeps on going on and on cause I have to edit a lots of catalog.The files are big you know for graphic design.I use them also in my pc with XP wehn I'm home and then in the laptop when I'm at work with Vista.I took care of the problem in the PC by downloading moveonboot and erased those files but seems like Vista is not compatible with that moveonboot.WHAT CAN I DO?I feel like getting rid of vista and putting XP on my laptop.If so also how to do that.Thanks,pELAOPS: OH! I forgot I also went to safe mode to try to erase those files and I couldn't erase them.I also downloaded unlocker but it won't work either.I bought it in circuit city late may.I have a hardware insurance like if it brkakes down or coffee spills oever it but not the software.Although, I'm very unsatisfied with this program. SUCKS!.
