Cannot connect to internet (Data)

[Envycycles]

I just installed Radio 3.42.5 and dcd 3.3.4 on my sprint mogel and now When I try to get on the internet its says "cannot connect with curent connectionsettings. to change your connection settings tap setting" I hit settings and dont know what to do from there.
samething happens when i try to sync the mail.
Another thing is I can not get into the EPST I type ##778# or ##778 and nothing happens.

Any idieas?
