Turbo Lister Problem

Hi - I am having dreadful problems with Turbo Lister - anyone give some advice? I have windows 10, don't use Ebay that much, but now is almost impossible to use.

 

1.   I cannot do a back up - crashes out

2.   Is incredibly slow - can take over 2 minutes between key stroke

3.   constantly comes up wioth message saying 'not responding' - just have to wait it out. Sometimes can take up to 4 minutes to 'respond'

 

Would like to do a back up, wipe it and start again, but to scared that I will lose everything, particularly as every back up crashes out.Smiley Frustrated
