I signed up (paying subscription) and then I was hit with a white screen and couldn't do anything. I had to contact support and they give me a long list of troubleshooting issues for the "white screen" so they are well aware of this issue, but instead of fixing it, they want the customer to perform all these extra actions to use a service paid for. I finally ended up using a different browser cause Google Chrome wasn't working, and after all that time wasted, the receiver of the file I sent wasn't able the receive the file due to another error. What a complete waste of time. Avoid this site.
