SOAPUI |Error wihle importing a wsdl file

Hello dear Smartbear community,

i have the following error while importing an original WSDL file (http://www.osci.de/xauslaender1190/xauslaender1190BAMFABH.wsdl) and don't know exactly what the problem could be.

i would be happy if you could help me because I need this use case quite often.

Thanks in advance
