Brother printer driver broken

Hi, I have Windows 7 Home Premium 64 bit.
My Brother p-touch QL-500 printer is USB connected.
My main hard drive, the C drive, is an SSD drive, just in case that matters.
My p-touch printer, which I use for address labels,worked OK until I installed it on a new PC, using the installation disk.
The installation seemed to work OK, until I tried to use the machine.
Then a message flashed up to say the drive was broken.
I re-installed it from the Brother downloads page and it seemed OK.
then I found that if I tried to make an address label it was OK until I got to the part where I click on 'check media'.
Then a message flashed up to say 'printer offline or no media', neither of which was correct.
If I ignored the message and continued through to the print stage, nothing happened except that the green light on the machine flashed rapidly until I turned the machine off.
The label position-er or reset button works fine.
Seemed like a software fault, so I uninstalled and re-installed the driver from the Brother downloads site. Now I again get a message to say the driver is broken.
I'd be grateful for any advice.

Hi fireberd. Thanks for your reply. Yes, I'll try different ports and look for a new cable. I'll post a message about how it goes. Thanks again,.

Hi WHS. Yes, I know what you mean. Their support team were not very helpful. Thanks for your reply
