NWI,
You may want to join the Indiana Gun Owners forums, they have a long running thread on the waiting time for a license:

It seems like the current wait is similar to yours. As I recall, your old license along with the receipt from your renewal can act as a temporary license until you receive your renewal, but you should probably confirm the current rules regarding this.
