PHP Error "Trying to get property of non-object in"

Hi!

Seems like a great plugin and exactly what I need.

However I can’t get it working.

Here’s what I get with wordpress debug mode on:

Trying to get property of non-object in /wp-content/plugins/geotargeting/includes/class-geotarget-functions.php on line 102

So this line to be exact:
if ( strtolower( $user_country->name ) == strtolower( $c )|| strtolower( $user_country->isoCode ) == strtolower( $c ) ) {

Some help would be very much appreciated.

To give some context:

When I enter this:

[geot exclude=”IN”] Will show to everyone except India users[/geot]
[geot country=”IN”] Should be shown in India [/geot]
[geot exclude=”US”] Will show to everyone except US users[/geot]
[geot country=”US”] Should be shown in US [/geot]

Will show to everyone except India users
The page shows this:

Will show to everyone except US users

Thanks!
