I tried many suggested solutions mentioned here and in different articles until I came up today with a solution,,
1. enabling history:
- go to SAP login
- customize local layout (Alt+F12) [the colored screen icon]
- options
- local data
- history
- change history status to OFF > apply then again ON > apply
2. Clear History
- in the same location where you are just click "Clear History" button
3. Delete old History data:
- in the same location also, go to the input history path and copy it
- go the browser and paste the path
- you will find an MDB file usually named "SAPHistoryXXXXX"
- delete this file
- close all open windows including SAP GUI
- run SAP and login, problem should be resolved
