The error seems to be a line of bad code, but I've never had any luck exporting from Blender, or editing python scripts, so I don't know how to fix that, sorry.
For the curse however, I gotcha! Basically, you'll want to write a script to add or remove the player from the curse's faction.
A script on the shrines can remove it, and start/reset a timer or decrease a 'days passed' counter, that will re-add the faction when it runs out.
You'll also want a script to start your quest after 30 days, and maybe one to disable the shrines after it's complete to avoid reacquiring the curse accidentally.
There are TONS of tutorials for both, so just use google and pick something typed out or on youtube, depending on what you prefer.
A good place to start, in my opinion, is the link below. The narrator is kind of unorganized, and he does make some mistakes, but it was a great primer for me when I was figuring out the basic quest system:
Another great way to learn or practice scripting, is to just copy and edit existing in-game effects.
Copy the script from a normal shrine and edit it to add your faction instead of its blessing, change the message text that comes up, etc.
The reanimation spells have timers, so look into those, too.
NOTE: If you haven't already, you'll need to unpack the Scripts.rar file beforehand, or you won't be able to open the script sources.
Depending on how/where it extracts to, you may need to move it into (or first make) the folder Skyrim->Data->Scripts->Source.
You'll know they're in the right place if "Edit Source" is no longer greyed out in the CK. If it IS, you need to move something up or down a level.
