rawprawn Many thanks for your replies. Despite several attempts at installing older versions of Roboform, I am still getting the same problem. I have unintalled using Revo on the advanced settings, and then used CCleaner to tidy up the registry. I have also searched for any roboform files that may have been left over and deleted them. I have reinstalled one of the older versions. v6.9.93, but the same thing happens. Failing all else I will have to use something other than roboform. Is there a way of reading the data stored in Roboform?
