Table adapter ???

Hay,

i have a little problem.I'm using vb2005 and sql2005.The problem is
this.
When I import tabels from sql,vb creats table adapters and that works
fine,but when i create a table in vb in DataSet then vb won't create
table adapters.I had this problem before but then i simply restart vb
and all was fine.This metod dos't work now,knows sambody where's the
bug?

thanx

.
