Upload ATC 2007 EA Problem

 
When I try to upload EA to my ATC 2007 profile, I get message that "The file name may only include latin letters, numbers, hyphen (-) , dot (.) or underlined (_) characters".

Here is my upload path with EA name. C:\Program Files\MetaTrader-MG\experts\Bogie-ATC2007-1.ex4

I read in the Russian forum that MetaQuotes on 27/08/2007 started testing paritcipant EA files. Is this the reason I can not upload EA file today?

Additional information. The above reported attempt to upload EA was with Windows 2000 Internet Browser v6 (current version). I tried to upload EA with Windows XP Internet Browser v6 and got same message. I then tried with MAC Safari browser v2.0.4 and it uploaded OK.
