Problem Launching LoadUI 2.6.7 and LoadUI 2.7.0

I am having a problem launching LoadUI 2.6.7 or LoadUI 2.7.0. It worked on my laptop about a month ago, which is running Windows 7 Enterprise... then approximately three weeks later I tried launching 2.6.7 and it gave me the error "A problem occurrec during startup and LoadUI needs to restart" and it gives you the option to restart or quit. I then uninstalled it, rebooted and re-installed it as administrator and I still get the same error message upon launching. I then tried unstalling that and loading 2.7.0 (as administrator) and it gives me the same problem. Any suggestions or help would be greatly appreciated. Thanks for any help/advice in advance!!
