Well, this is what is wrong, in my humble opinion. The ASP code that you are having trouble with runs on the server of the website. What is happening is that this code contains a time limit, say for example 20sec. When the user tries to upload something if it is not complete inbn 20 secs, the server stops trying to complete the transaction and you have to start over. This prevents the server from trying to upload indefinetelly and thus crashing thr system.
This time is usually set by the designer or a webpage to a logical time frame like 90 seconds or a minute. If the server though is overloaded and you pass the time limit you get this message and you have to start over again.
There is a page in Microsoft�s support that described how to change this, but it really wouldn�t do anything for you as you are not the one controlling the ASP. Plus, you need to have a special internet control manager program installed that only web designer really use, it�s not probably included in standard Windows version ( i don�t know, I haven�t checked).
My guess is that the continuous efforts to upload are cramming the server. Give it a rest and try and upload at a time that not a lot of users are active. If nothing else works, contact Victor with your problem and he might be able to do something about it.
Sorry for the long-windedness and for the fact that I only told you what the problem is, not really solved it....
