Problems with cfftp

[ToonKayser]

Using ColdFusion 3.1 an error message occur
while trying to access via cfftp.
This did work fine, but all of a sudden this message occurs.

An error occurred while attempting to process a CFFTP tag:



The error occurred on (or near) line 55 of the template file
C:\CFUSION\bin\CFTags\cfftp.cfm.


50: <cfexit>
51: </cfif>
52:
53: <cfelse>
54:
55: <!---Create a new object and cache it --->
56: <cfobject name =&quot;ftp&quot; class=&quot;ColdFusion.CFFtp.3&quot;
action=&quot;create&quot;>
57: <cfset &quot;caller.#attributes.connection#&quot; = ftp>

Error trying to create object. Klasse nicht registriert


The custom tag CFFTP (C:\CFUSION\bin\CFTags\cfftp.cfm) was called by
template C:\CFUSION\bin\CFTags\cfftp.cfm, line 55l.

Can anabody help me with this?
I guess some dll-file is corrupt or missing.
