Bank statement won't open

I can't open a bank statement. Other banks, no problem, (all other adobe PDF's from wherever, no problem, they all open) this bank, it looks like it wants to open, flashs and then blank. Month after month they post my statement and I can't open it. I've cleared cache, cookies, browser history, cache images, shut off my firewall, restarted PC numurous times. The bank is no help, they say there is no problem and they can open my statetment/s no probem.  I'm not tech savey and I don't know what else to try. 

Any ideas?
