Latest Update leads to error message on startup

[kathode]

Hello,
since updating to 1.5.5 I am getting "There is a problem to open the catalog, check your settings or folder used!" upon starting XnView MP everytime. My Catalog settings are attached.

Any pointers on how to fix this?

Thanks!

your catalog is stored in 'Program files' but it's read only folder

Okay, I now manually changed it to store the catalog in my Documents folder. Still confused as to how this problem came up. But thanks.
