TOM 7 Rory, what you can do is make a new player and import your old solutions. Create a new player and register. Then go to load, then triage (or anywhere else you want to import solutions). Press ctrl-0, then type the name of your player file (you might need to look inside the package to see this; it ends with .esp). Eventually you'll be able to select it from a menu, and player renaming is coming too! But this will work for now.
BTW, if you use the feedback link from escape.spacebar.org to communicate with me I'll find your questions faster. =)
