I am a bit confused by the download limit: as far as I can see on the account details, the download limit for a standard account is 100 files within 24 hours, which is usually what I get when I don't upgrade my account. However, I sometimes get blocked after just 20 files (for example, today). I didn't download any files yesterday, so I would have thought I could download up to 100 today.
There may be a logical explanation to this, but I would like to know a bit more, because I am concerned someone else may be logging in my account and using my allowance (I did change my password once or twice, but this keeps happening).
I sometimes upgrade to get 500 files per day, but now I am worried that somebody would steal my allowance, so I would like to get this clear before going ahead...
I could find no activity history (is it available somewhere?), otherwise I would check by myself before bothering you guys.
