Ruaidhri - sorry that I can't help. I had a serious problem with the launcher last year and had to eventually copy the install from one computer to another to fix.
Intrinsical - I probably have enough costume slots; however, I took that offer. As you stated, it's a steal.
Jim Gamma - IMHO, if you don't have plans for the ship there is no reason to keep it. Use the funds to outfit your other ships or buy dil.
