Hello,
I assume you're using the Linux download of LR 1.5, it's the only
version where I forgot to include the config file. Please also
download patch 1.5.2 and extract its content in your 1.5 folder;
replace all existing files with the new files from the patch. The
patch includes a config file.
Get the Linux patch here:

Best regards,
Mario
