If it keeps up the "Not responding" issue then delete Absinthe and all it's files.
Download the latest always from the official greenpois0n website:

Make sure you download it from Mozilla Firefox or Google Chrome. Not Internet Explorer.
It is best to download from a different browser from which you used the first time, or from a guest account on your computer. I don't know why that makes it work...but it does.
Save Absinthe to your desktop...double click and wait for it extract the Absinthe folder.
Now open the Absinthe folder
Right click on Absinthe.exe and click "Run as administrator".
If there is a blue and yelled shield symbol on the Absinthe.exe file...then permissions are already set to run as administrator.
But basically XamDam is right...if the jailbreak process just stops in the middle of the jailbreak then you should restore "setup as new". The jailbreak.
But DO NOT restore from the latest backup...assuming that the last time iTunes backed up your phone...your phone was half jailbroken..and you do not want to restore from that backup.
Choose an older backup files...from a different date...or better yet....just don't restore from backup at all..and start from scratch.
That is the best way to do it...but most people prefer to restore a backup.
I personally do not restore from a backup...and never will. I backup all my data my own way..and I do much better then iTunes IMO.
