Glad somebody wrote in about this - I've been having trouble downloading from Simviation for some time, say at least a week. I can go to the Simviation site, open it, find something I can use, and start the download process. What then happens is a message arrives in red, to the effect that I can only download two files simultaneously. If I am getting this msg in error, try cleaning my internet hold and cache files, or use another server to download. What makes this interesting is I get this message before I've even started a download. Went to the Simviation forum to report it; I got a message back saying the same things the red msg said; in other words, clean my machine and try Firefox or something else; it's on my end and not on theirs.
