Can't download rar files to my storm. I'm using Opera. confused???

[pdunc44]

I'm using a Storm 9530 OS 5.0 and trying to download a 113 MB media rar file using my Opera 6.1 Browser. The download window appears and asks where I'd like to download to. I enter SD card and than nothing.... Later it comes back with a pop up that says download failed. I am able to download zip files of the same size or larger from the same site (Hulkshare) of which I am a member. I've read where others can download large files of almost any size using Opera browser. Am I missing something? Do I have some settings in properly set? Can anyone offer some help or explanation? Thanks in advance.

I would not even try this myself using cellular network, but, I have been able to do this using WiFI and with the BB Browser. Don't use Opera so I can't answer anything regarding it's functionality.
