File - new items -> Error: Parâmetro Incorreto

Olá, tenho licença do Delphi 2007, estava funcionando ok, mas devo ter mexido em alguma configuração ou arquivo, do Delphi ou Windows, que passou a dar esse erro no Delphi: quando tento criar uma nova unit, form... um novo item, gera o erro "Parâmetro Incorreto", com os seguintes detalhes:

Isso também acontece no tools - repository, e talvez em outro lugar que eu nem tenha testado ainda.
Já desintalei e reinstalei, não funcionou. Não mexi no registro do windows para apagar chaves do codegear. O delphi voltou nas mesmas configurações, com os mesmos últimos projetos.
Deve ser algo simples, se alguém puder dar uma ajudar nessa resolução...
Obrigado!
