"Unable to open. File corrupted" error on my sis file.

[Leo_75]

Hi there... i just got a Nokia N73. I created my sis file using the swfpack ( i have about 100 swf files with my main.swf)
I do the installation without any problem untill i try to run it.
When i try to run, i get the following error:

"Unable to Open. File corrupted".

Any idea why i am getting this error?

Thanks.
Cheers.
Leo.
