SQL Datasource - password field "greyed out"

Hello,

I'm using an older version of RDM (support license expired, trying to convince our manager to purchase a new one), but I'm hoping you can help me with my issue.

I've re-installed my laptop and can no longer use remote desktop manager with a SQL datasource. I add the SQL datasource and can enter all the required information except the password field in greyed out so I cannot enter the password (see attachment).

I've tried this on versions 6.1, 6.5 and 6.7 (our upgrades only run until April 2012)
