I was sailing along just fine after my above problem but then I hit a "game over". At first I was thinking it was just the end of the game but it seemed to abrupt so I looked at the walkthrough just enough to see what I did wrong. Tried some that night to proceed further with no luck. Took a break from the game yesterday but have been trying half the day today to get somewhere in it, again with no luck. I even looked at the walkthrough and the UHS hints. Seemed to be doing what I was supposed to be doing but something was nagging at me.
Argh is for 2 things. Getting lost over and over in the jungle even though I tried to follow the directionals in the walkthrough (not helpful to me) and
an inventory mix up. Since I can not tell what the H the stuff in my inventory is supposed to be, it turned out that I had a radio with me instead of a portable transporter because when I was trying to get the last crystal, I used both items together (not knowing what exactly they were and what I was trying to do). What is supposed to happen is you use the radio to make a high frequency sound to break the glass in front of the crystal and then you no longer have the radio in your inventory. Because I used the 2 items, the radio stayed in my inventory but I lost the transporter. I only figured that out by replaying that part of the game and NOT using both items (along with the walkthrough telling me what the darn items were).
I'm now back on the mother ship at the end of the game but taking this break trying to decide if I should just wait until tomorrow to finish it up since I am a bit frustrated right now (mostly from being lost in the jungle). Was hoping maybe typing this out would help me.
