Having downloaded TopStyle 5 and paid for a licence and being keen to try it out, I deferred importing the settings from TopStyle 4 to a later date. That was today and I exported my settings from TopStyle 4 and imported them into TopStyle 5.

After I had done that I was asked for my licence key again. Would it be possible, when importing from an earlier version, not to overwrite the licence key? It's only a minor niggle, but it would be nice if it could be fixed.

Thanks,
Roger
