Sorry if this is a totally noob question, but I really need to know. I have installed Acronis Version 10.0.4871 about a year ago and made a backup image. I was able to use this image to restore my computer a few times without no issue (I was using the Image Startup recovery disc) But a few moths ago, the Startup recovery disc started to behave weirdly, (It couldn't find my SATA drives in Full version and the safe version would hang and freeze randomly) I upgraded to Version 10.0.4940 and the problems seems to stop.(although I have yet to restore my machine with the upgraded version the the Startup Recovery disc) I am wondering Since I created the image with 4871, will I encounter any compatibility issues when I go to restore with the 4940 Version of the recovery Disc? Any information on this matter would be greatly appreciated. Thank you for your time.
