Recently updated version of the GUI and I lost my connection. Copy the configuration file and do not lose connections.
The first step is copy the file saplogon.ini ubicate on the folder C:\Users\ID\AppData\Roaming\SAP\Common
from saplogon.ini to saplogon.old
The second step is install the sap gui version, and when the installation will finish rename the saplogon.ini file by the file copy with the connections content
from saplogon.old to saplogon.ini
That's all folks !
