I'm afraid you can't. Here is why:
1. LinkSeam WhiteLabel is only an up-sell or upgrade of LinkSeam Lite and LinkSeam Premium which adds WhiteLabel features in your LinkSeam app.
2. Since LinkSeam WhiteLabl only an up-sell or upgrade you must have LinkSeam Lite or LinkSeam Premium and LinkSeam Agency in your account first in order to buy LinkSeam WhiteLabel.
3. Even if you buy LinkSeam WhiteLabel without buying LinkSeam Lite or LinkSeam Premium and LinkSeam Agency you wouldn't be able to use LinkSeam because LinkSeam WhiteLabel is depended on the standard and agency product. So, with only LinkSeam WhiteLabel you wouldn't be able to login.
Note: In case you bought LinkSeam WhiteLabel without buying LinkSeam Lite or LinkSeam Premium and LinkSeam Agency consider buying the standard/main and agency product from our sales pages.
