All MSN keywords returning error

Google and Yahoo work fine, but all my MSN keywords all became NA starting a few weeks ago, I re copied and pasted the script (to make sure if there was any updates)... but still nothing. Below is the error message I get when clicking on an individual keyword, how do I fix?

<br />
<b>Warning</b>: Invalid argument supplied for foreach() in <b>mysite/digitalpoint.php</b> on line <b>218</b><br />

I've already moved it to that server from a previous one because of a similar error (maybe the same one, I don't remember at this point)... I'm running out of servers to run the script from... it's not like I run it all the time, I have maybe 25 keywords on MSN that I run about every other day?? Thanks for the help.

 

any reason why my server gets this error after a month or so? Like I said, I've already moved it once, and I don't use it that often so I'm not sure if/why I'd be blocked by MSN? I don't have any other server to move it to at this point..
