Topic: Update to Juicebox 1.5 failes

I tried to update the wordpress plugin from Pro-Version 1.2.0.1 to 1.5:
I downloaded the files with the link of my E-Mail (Pro Purchase).
Then I copied the jbcore folder to my ftp-folder and overwrote the existing files.
I deleted the cashes of my wordpress installation and the bowser cache.

Unfortunately the version information did not changed to 1.5.

I wonder why there are some more files in the wp-juicebox folder as in the one of the "pro download" (also in the "lite download").

How can I update?

Re: Update to Juicebox 1.5 failes

You can download the latest version of WP-Juicebox (v1.5.0) from the plugin's support page here. (WP-Juicebox is not included in the Juicebox-Pro zip package.)
Install the plugin following the Installation Instructions (in the link above) and upgrade it to Juicebox-Pro (using the 'jbcore' folder from your Juicebox-Pro v1.5.0 zip package) by following the Upgrading to Juicebox-Pro instructions.

Essentially:
(1) Download WP-Juicebox v1.5.0.
(2) Replace the plugin's 'jbcore' folder with the one from your Juicebox-Pro v1.5.0 zip package.
(3) Upload the 'wp-juicebox' folder to your WordPress 'wp-content/plugins/' directory, overwriting your existing 'wp-juicebox' folder.

After doing this, you will have the latest version of both WP-Juicebox and Juicebox-Pro.
