Reference Pack not available to select?

Hello,

i have read the below post and tried to follow to troubleshoot the issue i have with reference pack not available in VCA change settings. Initially when i installed HPSIM 7.2 (new install) it worked but i have no idea what stopped it from working. All i can see in VCRM there are three more Support packs downlaoded and intially i only had 3 ?  see attached.

Can someone please help me with this as i have been pulling my hair for days...!

Thanks
