php4apache.dll not loading under W98/Apache/PHP4.0.4

I'm using windows 98, Apache 1.3.19 and php 4.0.4, and it used to work fine until some weeks ago. Now when I start apache, with php configured as a module, it gives me the folowing error: "Syntax error on line 190 of c:/programas/apache group/apache/conf/httpd.conf: Cannot load c:/programas/php/sapi/php4apache.dll into server: (31) A device connected to the system is not working:" (Last sentence is a translation from portuguese). First, it gave me an error because of odbc32.dll, but the I de-installed and re-installed Access 2000, and it started to give this other error. It has always worked fine before with this config. The error must (at least that's what i think...) dll related.
