paypal pro add-on conflict

hi,

i made a new install of gravity form on a new site.

when i install the paypal pro add-on, there is the register message on it.

when i uninstall it, the gravity form plug-in has no registering message.

licence and paypal pro api are reconized.

i can't use the new gravity form install with an older xml saved form.

how can i fix it ?

regards

yes correct i have the latest gform and paypal pro add-on.

i use wordpress 3.5.1_fr

i know there is a new release of wordpress but in the back end it doesn't purpose me an update.

do i make an update of wordpress then ?

ok so,

i made a so long form on a site and export it.

i transfered the site on an other hoster.

i installed wordpress and the plug-ins like the older site was.

when i installed the two latest release of gravity form, i had not acces to add-on page.
so i installed the latest gravity form release (1.7.5) and did the same.

no form on the page appear.

i took the latest paypal pro add-on here and this"Register your copy of Gravity Forms to receive access to automatic upgrades and support. Need a license key? Purchase one now." and still no form on the page.

paypal i configured, the shortcode is in the right page.
the preview is avaible.

what's wrong ?

yes i entered 4 times my licence, and when paypal pro add-on isn't activated, gravity form has not the message.

and this is the third same site i installed on different hosters, nothing change on the site it's just worpdress export/import and gform export/import.

edit : when i turn the paypal pro on sandbox mode, all api appear red but form appear on the page.

edit 2 : i unchecked 'IPN is setup in my PayPal Pro account.' and it works then. but still have the register licence message.

i release a new and fresh install of wordpress, only put the plug-ins...

still no extention page access in gravity form...

i open the site july 1st thank you to help me for this incredible issue
