I guess I missed this post. Sorry!
It is a known issue that the file selection dialog will not work for some people. It has been an issue for a very long time, but I was able to work around the trouble for a while. In the past few years my workarounds have been rendered ineffective. Luckily it only happens to a select few.
In version 3.4 (I believe) I added a sort of "backup" file selection dialog for those the standard one no longer works. It's a bit of a hack, but it gets around the issue.
I'm using 3.3.1 if an update to the current 3.4.3 would resolve the issue would the tournament files be back wards compatible or would I have to update the other laptop
The TD is backward compatible, but what you're referring to is actually
forward compatible, which the TD is not. Files saved in 3.4.3 likely won't work with version 3.3.1, so it sounds like you would have to upgrade both.
On the positive side, this issue is fixed in version 3.7. It's still in beta testing, but it's pretty solid at this point. Check out the beta testing forum.
