Downloading and applying a zVM fix

[Horlick, Michael]

Hi,
 
I am at a disaster recovery planning site right now. Running z/VM 5.2.0 Service 
Level 0601 2nd level. We have been getting a PRG004 hard abend and it appears 
from looking at IBM Service Link this has to do with APAR VM63987 and there is 
a fix for z/VM 5.2, namely UM31750 since it is seems to be abending in 
HCPGSSLA.  
 
I tried to do an online order and the system comes back with "There are no 
valid PTF(s) in this order".
 
How do I get this PTF? I am more familiar with VSE.
 
Thanks
