Controlling another team.

Ok I started using the Memphis Grizzlies as my dynasty but as two seasons went by I decided to switch to another (MANUALLY).

I went to teams.dbf and edited what I thought I need it to change...It worked but the problem I have is that I still receive the e-mails from my old team and I never get the e-mails intended for portland...Is there something I can do to fix this?

Unfortunately there's no workaround for that. Switching teams via dbf editing is pretty glitchy to say the least.
