I have to admit I'm not familiar with that product but we can do some basic trouble shooting. First double check with the manufacturer that it's designed to work with Snow Leopard. Your profile indicates you are 10.6.3, the most up-to-date version of SL is 10.6.5, so see if the software will run on 10.6.5. If it is verified to run, then I'd recommend opening a new user account, don't make any changes to it and see if the software installs and runs OK in that account. If it does they we have narrowed the issue down to your user account, if it doesn't then it's a system wide problem.
Let us know what you find out after you have checked with the manufacturer and have run the software in the new user account.
