I purchased Gravity Forms newest version and downloaded it to my desktop then tried to install it per your instructions. I have version 1.3.11 installed and want to upgrade, but I get this error:
Installing Plugin from uploaded file: gravityforms_22.214.171.124.zip
Unpacking the package…
Installing the plugin…
Destination folder already exists. /home/XXXX/XXXX.org/wp-content/plugins/gravityforms/
Plugin install failed.
I replaced the actual name of the directory & website with XXXX. I have version 1.3.11 and it says a New version 1.5.1 is available, but I don't know how to get the automatic update and the install is not working. I entered my License Key that was emailed, but it is still not working. Also, I have several forms that are working (with version 1.3.11) and I don't want the new version to mess them up. I am new to WordPress and Gravity Forms. Thank you in advance for your help.
