PIe Register 2.0.13 Redirection not working

I have a private page which I reach by a form made with Pie Register (pie-login). To redirect the user on his page I use the plugin Peter’s login Redirect.
When Pie register is activated, the redirection does not function.
When Pie Register is not activated, and that I try to connect the user on his page with the wp-login of WordPress, it’s OK .
Can you tell me what is wrong ?
