The ']' expected near ',' error is indeed due to numeric format issues. The best way to fix it is for the plugin author to implement one of the various number format patches (basically saving numbers as strings and converting them back to numbers after they are read back in, bypassing the OS numeric format). I usually implement a slightly altered version of the Vindar patch. The original Vindar patch can be found at:
