Single Sign-On certificates on SAP market place doens't work ie11

Hello,

i was using sso certificates and they where working always. When they expired after renew them, they don´t work any more, the sap support url is correct and I didn´t make changes on my settings.

I´m using Windows 8.1 Enterprise x64 and IE 11.0.9600.18161, with Firefox it works but doens´t have the possibility to assign a name to the certificates and if your are using many to check every time wich one you need is just wasting time.

Any ideas?.

Thanks and regards.

Dario.
