It's too late to change now so contact a bunch of other software providers after tax season.  Most will give you a free demo copy of the software (or sometimes free full copy but without efile privileges) to evaluate.  See what meets your needs.  It's really going to depend on the types of forms you need most often for your clients.  If you do a lot of farm returns, for example, you might shy away from ProSeries who won't be ready to file them this year until 2/25 (even though they're due 3/1).
