Print Preview mail and fax error in Purchase order (ME23N)

Hi,

We try to 'Print Preview' a purchase order in transaction ME23N and it

gives us the following error:

' Call of USERNAME with XXXXXXXXX FAX Error occurred in R/3 in SAP

Connect'--> Message number XS008

And when including the email info it gives us this other error:

'Version USERNAME incompatible with version used'--> Message number

XS011

We have tested to send an email and it goes OK. The same with the fax.

Could you please help us with this error?

Thank you!

Regards,
