help with sound fonts

Can anybody help? I've got a sb live card with 128mb of ram. I downloaded a huge sound font that took ages and I was really looking forward to it, after about 3 hours it had finished downloading, I then fount out that it was paked with a funny program, so I downloaded that and unpacked (This took too long). Right, now I was ready to put it into the card, so, I open the sound font manager, increase the cache to max 9It goes up to 63mb on mine) and try to load the font, well, to my surprise the font is too big for my cache!!!! This annoyed me, so, can anyone tell me how I can increase my cache size without buying more memory, I only need 2 more meg as well for thisa font (look at that for sods law). Email me with answers, please
