|mmm - Sometimes some software requires one to run the setup again - and then (for some strange reason) there is also an option to "uninstall it"... when you run setup...|
Meanwhile - see if this helps. regularly recommended here and apparently very good...
There is a freebie trial version and that may be all you need?
Incidentally it's useful to make a note of passwords somewhere? Make a hard copy (write it down) and keep it/them safe somewhere (where you can remember too); and perhaps email them to yourself - with perhaps a slight modification so that only you can know the actual complete password or passwords. Store those messages in a saves folder in your online email account(s).
One method to remember passwords is to follow the example of many secure sites. Give yourself a memory clue that relates to the password. For example: in mail you save to yourself - you don't include the name - only a hint to it; and add some other letters/characters to the name of course for the complete password.
So if the password was perhaps Charles123 - your father's name was Charles - you would save the password details as "father" + 123, or "father"123. the " " are only for clarity.
You see the idea?
And if you're reasonably safe/secure about it all at home, no harm to paste "some" passwords on the base of your computer (if a desktop), or inside the battery compartment if a laptop?
