My game runs perfectly until I press the "enter" key.

[HiddenLives]

I am new to the site, and just downloaded Pleurghburg. The game was running perfectly up until the point when I try to access and search something on the computer, which requires me to use the "enter" key, causing the game to crash and giving me this message. I have no idea what caused this problem or if this is a common issue. Any help would be appreciated.

I wasn't sure I could tell anything useful here, but I dled the game just in case, and do not seem to be able to reproduce this.
Are there any certain actions that should be done for this error to occur?
I did this:
- At game start, used computer.
- Selected "Search"
- typed in some random letters and hit "enter" key.
A message appeared, telling me "there's no point in searching that right now". Game continued running as normal.

Perhaps, you could give more specifics about what you do?
Does this happen all the time?
