Oh? Which OS are you on? I've used the plug-in before and haven't had problems, although not in while as I usually just use the copy uv to clipboard feature in the coordinate editor.
Also, I just posted this up:

I wrote this awhile ago and I've been meaning to post it. I do most of my textures as vector art. This plug-in will export the uv map to a Corel Draw-compatible DXF file.
