Spreadsheet wont copy to cd
Hi I am having a problem copying an excel spreadsheet onto a cd. When I tried copying the file onto my cd rom if would cause my system to freeze up. I emailed the spreadsheet to myself then went to a friends computer to try and copy to disc and his system froze up as well. System freezes when I click on the cd-rom drive from my computer..... actually it says to insert a disk into the cd rom drive and when i insert disk the system locks up. Any help would be appreciated. I havent tried any third party software like roxio but if someone can tell me where online i could get some kind of software that would fix this problem that would be great. Thanks again for any input.
