[Typo3] Press Center problem with filesize or memory

[Vincnet]

Hi!

This happens when there's a file of 17MB to be in the Press Center 
download area (the extension is called "cwt_press_center"):

Warning: fread(): Length parameter must be greater than 0. in 
/home/sites/site9/web/site/typo3conf/ext/cwt_press_center/tools/archive.php 
on line 439

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to 
allocate 18278625 bytes) in 
/home/sites/site9/web/site/typo3conf/ext/cwt_press_center/tools/archive.php 
on line 439

Anyone any ideas? Sebastian (one of the creators) is not sure yet about 
the problem, but it looks like a memory bug in the archive.php. As far 
as my investigation went, I can't see a spot where a filesize is set. 
Further, it seems to go wrong at the point where the zip is generated 
(which I actually don't need, so if someone knows how to skip this 
function).

Thanks, Vincent
