certificate installation

Hi,
Trying to install A PositiveSSL cert (RB433,435 ROS6.10) for use with Hotspot clients

They’ve sent me three certs :
1: MyDomain cert,
2: Indermediate cert and
3: CA Root cert

I imported all off them with that order and last I imported my private key using winbox

The support-man told me that the common way is to install
my Domain certificate with the key and then a bundle,
which actually is a file containing the two other certs.
Both installations give the same results as in the image below.
They also give instructions for many web-servers but nothing about MT web Server

Is my setup ok?

I enabled certificate logging and this is the output:

18:20:59 certificate,debug looking for CRLs in cert_1
18:20:59 certificate,debug found CRL: http://crl.comodoca.com/PositiveSSLCA2.crl
18:20:59 certificate,debug looking for CRLs in cert_2

18:22:01 certificate,debug updating CRL: http://crl.usertrust.com/AddTrustExternalCARoot.crl
18:22:02 certificate,info got CRL with bad signature

Since the documentation is obsolete, I would appreciate some help
Thanks in advance
