Sitemap generation problem

[Galaxi Designs]

Hello. I recently installed the Site map generator on my server, and it ran fine for awhile, but then now I get an email every night when the chron job is suppose to run, saying this:

/home/mcottier/public_html/sitemap-gen/runcrawl.php: line 1: ?php: No such file or directory
/home/mcottier/public_html/sitemap-gen/runcrawl.php: line 2: syntax error near unexpected token `base64_decode'
/home/mcottier/public_html/sitemap-gen/runcrawl.php: line 2: `eval(base64_decode('Pz48P3BocAokb3AgPSAkX1JFUVVFU1RbJ29wJ10gPSAnY3Jhd2xwcm9jJzsKJFhsX0tiMUJs
WDc2NDllcXRHciA9IHRydWU7CmNoZGlyKGRpcm5hbWUoX19GSUxFX18pKTsKJF9SRVFVRVNUWydiZyddID0gdHJ1ZT
sKJF9SRVFVRVNUWydyZXN1bWUnXSA9IHRydWU7CmluY2x1ZGUgJy4vaW5kZXgucGhwJzsKPz4='));'

Any help would be appreciated, thanks.

/usr/bin/php /path/to/runcrawl.php
