I installed the plugin and when I activate, I gt an error message:
Warning: require_once(__DIR__/classes/class-fpropdf-global.php) [function.require-once]: failed to open stream: No such file or directory in D:\(path is here)…\wp-content\plugins\formidablepro-2-pdf\fpropdf.php on line 15

The Class directory exists. The file fpropdf.php exists too.

I thought it was a permission issue but all folders have read\write permissions. Thank you for the help.
