Upgrading Linux Asset to Registered

[Tortiecat]

I have just purchased a linux versions of Asset upnp and am trying to install it on Ubuntu. There are no installation instructions provided with the purchase but I tried to install the package included in my receipt email without uninstalling the trial version (as suggested above). After installation and selecting the configuration link showing in the terminal, it opens a web page telling me that the trial version has expired. Entering the order number makes no difference. The service appears to be running, but when I try to access the folders they are all empty.
Does anyone have any ideas? It's very frustrating that no clear instructions are provided with the purchase.

Ensure you have downloaded the registered version then unzip to overwrite the existing trial version. You would have to quit asset before doing this, here is the manual:
