I don't understand. HOWEVER, HAVE NO CONTACT OR COMMUNICATION WITH THE PERSON ON THE ORDER!
Also, please go into more detail. Perhaps that will help me understand more to give a better opinion.

Your ex-wife lives in Ohio?
Hmm.... I wonder how bad the issue was between you two. Then again, I reason if she was willing to talk to you an attempt to hustle you out of $3000 USD, then the issues were not so bad or you would have been in a jail cell by now: I'm assuming you've unknowingly violated the restraining order. So, I suggest you know what those restraining order terms are, so that you do not violate the restraining order. If your ex-wife lives states away from you and you're in the state where the order was filed, then I assume that you could make a motion to vacate and dismiss the restraining order. Because if you do this, and your wife wants to contest it, then she is going to have to take a trip a few states toward where the court proceeding to vacate and dismiss would be: She could possibly use some telephone service to phone into court; but I'm going to roll a die and assume she's going to be too incompetent to do that (older individuals tend to be technologically incompetent).

So, maybe you could get away with things by making a motion to vacate and dismiss. It's a worth a try. However, if you're dead serious about it, you may want to take some time, do some research, and generate an evidence based argument as to what has changed since 1995, that you're no longer a threat to her, that she's no longer part of your life, that you don't want her to be part of your life, and discuss how the restraining order is a burden on you (You may want to bring proof/witness of the US Border issue), AND THEN make the motion to vacate and dismiss with arguments and evidence on the court day hearing.
