TickyTacky,
You may want to note that your expectations on Beta software, seems to be very high. Beta software is software that isn't regarded as complete. The software is merely used for testing purposes to remove any errors that are outstanding.
Therefore, everything won't work first time round. This get reported to Auran, then is fixed in another build which is then sent out to test.
The other problem you may have, is you don't have a working BETA key, for TRS2009 Beta, you must have a working BETA key.
If you do have a key, what are your system specs? Are you running Windows Vitsa? If so, right click on the TRS2009 icon and click properties, click compatiblity and then check "Run as Administrator", then press OK and re-enter your key.
Have you updated your drivers? If you have, what is the date on them? (Bear in mind, anything older than 1 month is considered old!)
(You may want to note that a lack of system specs, doesn't help any of us, understand the nature of your problem, we aren't mind readers!)
Edit, the beta has an expiry date, it will not work after I think, the 7th December 2008.
