I would suggest a newer version of the 7.0 client.. The most current 7.0 client available is 7.0.161. You should also make sure that the TE client, when installled, is installed into the default locations.
If this continues to happen on the newer versions of TE, you should reach out to Motorola as they currently support the Wavelink TE client, pre-licensed versions on the 9090 gun style hand helds.
