Note about the
Illegal Access
message. It is (very likely) related to incompatibilty of the currencies.php file of 1.2.x and 1.3.x versions. And the pricelist version you are using includes a 1.3.x currencies.php file.

Price list 1.2.3 does not require edits to this currencies.php file, or to any file, so better try that version instead!
