I played pre CU/NGE as well. I recently gave SWG another go (the veteran 30 day trial), and I'm on another trial right now (33 free trial for smugglers). The game is a bit more polished now, although I still miss how the game was pre CU.
I'm guessing you started up a new account for the trial, but do you still have your old account? If you still have access to it you should have a veteran trial that can be used for up to 30 days (pretty sure it still works).
I don't think I'd play the game if I couldn't play on my original account, just a lot of history with it. I'm still a bit mad that I gave away 90% of my stuff to my guild before I quit after the CU. I could have been pretty rich right now, but oh well :/
If you're still playing (I noticed it's been 14 days since your post xD) let me know, I have a low level char on bloodfin, along with ~20mil credits. My main char is on scylla though.
