What is this decoder limit?

[chas2003]

I saw a message after a download
you are allowed to decode 15 files since your last update.
This number of decodings is exceeded.
I am using
Mulitidecoder 1.0.0.42
But I have used many more than 15 decodes since I updated to this version. Can anyone here explain what is going on and how I get past it please?
Thanks,
Chas

@chas2003: The maximum number of decodings depends on your user status (leecher: 15; sponsor: 40; premium: 100/120). Unfortunately, you didn't mentioned your user ID, so that I can't check your status.

BTW, the current version of Multidecoder is 1.0.0.47. ;)

Thanks everyone who answered especially worforz and Pegu. I've upgraded now. I think it meant the limit is calculated by the number of points you spend not the number you have. I wasn't clear though about the automatic nature of it. Now that I upgraded once will it automatically upgrade me once a month for 50 points or do I need to do that every month from now on?
Thanks,
Chas -- no longer a leecher :>)
