I have a 6 year old PC running Nero version 6. It is simple to use and I love it. I ordered a new additional computer running Win7 64 bit. I need to find new burning software. The reviews on the new Nero products are horrible. I am not sure what to do. If I install another product like Ashampoo which is highly rated, will it be able to read the many multisession CD's and DVD's which were created with Nero 6? Will it be able to burn additional files on open session CD's and DVD's which were created with Nero 6? This is a major concern. If I decide to stick with a newer version of Nero what is the oldest version which will work SMOOTHLY with Win7 64 bit and where can I get it? I am interested in obtaining a legitimate version of an older program and I am willing to pay for it. I am not a big fan of cracks, warez, etc. Thanks for your help.
