I will pay for who can help me with this applet

Question

Hi!, sorry for my english, im spanish.
I have a big problem with an applet:
I�ve make an applet that sends files to a FTP Server with a progress bar.
Its works fine on my IDE (JBuilder 9), but when I load into Internet Explorer (signed applet) it crash. The applet seems like blocked: it show the screen of java loading and dont show the progress bar, but it send the archives to the FTP server while shows the java loading screen.
I will pay with a domain or with paypal to anyone who can help me with this problematic applet. I will give my code and the goal is only repair the applet. Only that.
My email: [email protected]
thanks in advance.
adios!

thaks for yours anwswers..
harmmeijer: the applet is signed ok, I dont think that is the problem...
itchyscratchy: the server calls are made from start() method. The applet is crashed during its sending files to FTP server, when finish, the applet look ok.
The class I use is FtpBean: http://www.geocities.com/SiliconValley/Code/9129/javabean/ftpbean/
(I test too with apache commons-net, and the same effect...)
The ftp is Filezilla in localhost.
This is the code, I explain a little:
The start() method calls iniciar() method where its is defined the array of files to upload, and connect to ftp server. The for loop on every element of array and uploads a file on subirFichero() method.
Basicaly its this.
The HTML code is:
<applet
       codebase = "."
       code     = "revelado.Upload.class"
       archive  = "revelado.jar"
       name     = "Revelado"
       width    = "750"
       height   = "415"
       hspace   = "0"
       vspace   = "0"
       align    = "middle"
     >
     <PARAM NAME="usern" VALUE="username">
