Data Direct Drivers for 4.x

Where can i find the latest Data Direct Drivers from SAP for Data Services 4.x. I used the ones from the link on the left hand side but when i try to run a job it fails and the DataDirect ODBC driver will put a QEWSD property in the odbc.ini. Based on what i've found online, this only happens if:

# Expired license file
# Wrong license file
# No license file

So i assume those drivers are not compatible. Can someone confirm? Is there a newer version? If so where can it be downloaded from?

Thanks for your help!
