So i'm getting these 2 errors when I try to type in the chat.

Devs, have you encountered this before?

Donating 300 TAC myself if anyone can assist me with the error above.

With this test. Go to the help window, debug window-console, put on the command line ""dumpprivkey <talkcoinaddress>" " without quotes or parentheses.
If everything goes right you back your private key. Well, now go to the Roaming folder and rename the folder talkcoin by talkcoin1, don't touch nothing more.
now do a clean installation with the latest version, Now go back to the debug window-console and on the command line you write importprivkey <talkcoinprivkey> [label] [rescan=true]
where you put the private key that has given you before and in "label" if you put a name to the address.
Now you must synchronize everything correctly, leave although this does not seem to work.
If this does not solve the problem, try to reinstall Microsoft Frontend 4.5 and C++ 2012 Redistributable 11.0.50727

You can make the block reward 1000, however if nobody is buying the coin it will cause further deflation.

Surely the best way to make this coin "profitable" is to create more demand, so the price goes up?

That would be MaGNeT then ;p

I have left 3 rigs on TAC, to help secure the network, however I've got 265k TAC now and I feel this is enough for now.

Can you get our Block Explorer working?  I need to put this on the list of tasks to do...
