Bigger files aren't loaded properly in Filesonic OK

[lo_scrondo]

Hi everyone,
                    I've discovered yesterday this program, and I immediately fell in love  . Today I wanted to make some "test" before switching to Premium, but, unfortunately, after doing the last update, all the files bigger than 10mb got lost ("Filesonic link not found").
I've tried to increase the timeout of the server (from 120 to 240 and 300 s), changed the buffer size (from 256k, that worked perfectly for me yesterday, to 128 and 64k - i'm on a broadband), but still the same problem appears (files smaller then 10mb: no problem).
It' a matter of FIU? It's a Filesonic problem? I need HELP!
Cheers

please, right click the red line after the upload fails and report it directly from my program

Zoom, I couldn't retry till tomorrow, 'cause I'm not on the broadband anymore this evening - now I'm using my home DSL but the problem is the same  !!!
In order to get a cue, I'm trying to upload with Filezilla..and the problem is still here!! The file gets wholly uploaded (all bytes), but after the "completion" Filezilla returns "Error 550 Can't check for file existence". I'll asked for help also in the Filesonic forum, but has anyone else got the same problem today?

filesonic is a bit overloaded
