[Q] Can't mount second Link2SD partition in CM 11 topic

I'm not a programmer - I just did my first root of my Galaxy S4 Blaze last month so please bear with me. I posted this under XDA Assist but that was the wrong place...

Yesterday I flashed a version of CM 11 that I had been using for a month with no problems because of some weird things happening with the newer CM 11 nightly I got a couple of days ago. This is what I'm now using again:

cwm-11-20150119-NIGHTLY-t769.zip

When I reinstalled Link2SD after flashing this ROM, I set it to Ext4 as it was before and I got this error:

"Mount Script Error - mount script cannot be created. Can't create handler inside thread that has not called Looper.prepare(0)."

Link2SD was working fine before I wiped the phone and reflashed the older CM 11. I tried uninstalling Link2SD, rebooting, reinstalling and then trying the other formats (Ext 2, 3) with the same result.

Not knowing what else to do I backed up my card and used Mini Partition Wizard to delete and recreate the partitions (FAT32 and Ext4) . Exact same error in Link2SD.

I tried making both partitions FAT32, same error.

I have no idea what else to try here. Can someone help me, please?
