Place that in Lua tags, it should also go in the Lua Question section.

[kaytaro]

place what in Lua tags? and sorry for the wrong area.

ok well right off the bat the error tells you that line 17 is whats causing the script to not run appropriatly,

so look at line 17

local crc_local = crc32(fread(base_dir .. fname, true))

the error is saying that crc32 is a bad argument.
