About the Service Pack and other updates

This is the most clumsy forum I've ever seen. Navigate the community and suggestion pop-ups are attacking me as I type!

Anyway, I have the CorelDRAW Graphics Suite X5 (Education Edition) I bought years ago via Journey Ed. Never thought much about updating, but I see there have been service packs. I just downloaded this one:

CorelDRAW Graphics Suite X5 (and CorelDRAW Premium Suite X5) Service Pack 3

Is this fine? I should also install this?

CorelDRAW Graphics Suite X5 Hot Fix 4

Please let me know if I am about to melt my PC. I'll wait a couple days for a response.

Also, do they keep updates for the legacy versions? I'm reinstalling CorelDRAW 11 on another machine, but cannot find a reliable source for the two Service Packs.

Thank you!!!!
