A89: Invalid certificate?




I have a hardware 1 TI-89
I installed ams 2.01 sucessfully when it first came out, then I went back to 
ams1.00. Now, I want to try this new kernel, phoenix and tetris for ams2.01. 
It installs all the way and goes to 100% but then it says "Invalid 
certificate, please check that this is the correct certificate for your 
calculator.". Then the TI-89 freezes. I have to take out the batteries and 
when I turn it back on all I get is "Press I to install code". I installed 
ams1.00 back so that is what I have now. Is there any way to get ams2.01 
back? I tried 3 times.
