Hi I am a newbee and have just installed this software and I am getting the following error Admin/licenseerror.php?licenseerror=Invalid - I had a problem with my installation and removed it and reinstalled. Entered the license and installed into the correct directory. Now I understand the problem, but I would have thought by removing the installation and reinstalling would automatically overwrite previous install setting. Can anybody offer any advice please.
