Sony pc companion back up and restore can you help please?

Question

Right, I have a sony xperia U and I have spent 8 hours!! Yes 8 HOURS! trying to restore contacts and call logs etc,.on pc companion using the facilities of which I thought was trust worthy and reliable to use. Basically using PC Companion I backed up all I wanted onto my computer from my phone and it is not restoring back onto my phone. I am not getting any futher than clicking restore phone. Nothing. I have lost EVERYTHING. How can it be retrived?
Is there anything that I can download onto the computer that reads dbk files and I can retrieve my contacts at least. NOT ARMAK phoneminder- I have tried that.
Before anyone refers me to other threads on this site I have read them.I have tried repairing-installing-shutting down-NOTHING works. Even blaming my computer-firwall and anti virus off!!! And to be honest the explainations have not been entirely clear. And telling people that they should have used the back up app on their phone is not useful when people that have already used the Sony service and have failed. The problem has occured on this software and it's not working, could someone clearly and consise- a step by step- 1,2,3 list to help in resolving this reoccuring problem. Maybe I might actually mark the enquiry as solved!!! So it will not have to be asked again.
Thank you for anyone that can help :-)

I know that this has been a long time coming for you but you're still fortunate as i already found the solution for your problem. I myself also experienced this problem when i tried to restore my backup files from my xperia ion to my new xperia z. Whenever i try to click migrate,i always a get a "sony pc companion not responding" prompt. What i did was i created a backup file from my new xperia z and since it was just new,the backup file came with a size of only 110mb. I then tried to restore it and again came up with another "sony pc companion not responding" prompt. I was so frustrated but instead of closing the program,i chose the "wait for the program to respond" option that windows asked. After several minutes,the selection for which files to restore came up. That moment i realized that the problem is that windows is stating that the sony pc companion is not responding which is actually false. It's just that when you're trying to restore a backup file that is too big in size,the program will take a long time to start the restoring process. After that,i attempted to once again restore the backup files from my xperia ion to my new xperia z which is quite big due to a large compilation of videos amounting to a total of 5.9GB. As expected,windows stated that the program is not responding but i decided to wait. It took around 10 minutes before the restoring process started. I was really after my important contacts that's why i never gave up till i finally solve this issue. I'm actually waiting for the restoring process to finish as i am typing this reply. Don't believe what mr. johan said  that you're backup file may have gone corrupt,you just need to be patient. Always remember that  perseverance is the key to success.
Hope this would help you,thanks for reading..
