[Therion] (no subject)

[Jonny Prouty]

Hello,

Hello, I've installed the win32 version of therion on a USB thumb drive, so
that I can use it on my computer at work. This has worked fine until
recently. Here is the error I get when I try to compile a map through
xtherion.

Error: can't read "xth(th_exit_number)"" no such element in array.

Here is the contents of the log file:

can't read "xth(th_exit_number)": no such element in array
can't read "xth(th_exit_number)": no such element in array
    while executing
"if {$xth(th_exit_number) == $xth(th_exit_number_last)} {
    set err 1
  } else {
    set xth(th_exit_number_last) $xth(th_exit_number)
  }"
    (procedure "xth_cp_compile" line 78)
    invoked from within
"xth_cp_compile"
    (procedure "xth_app_make" line 20)
    invoked from within
"xth_app_make"
    (command bound to event)

When I try to compile using therion directly from the command line, I get
the following error:

Press ENTER to exit!

Any idea what might be causing it? Thanks.
