Might help to know some more info, other than that you are having problems getting to, to work... that is.
Such as...
Where your install of LSH3 is... to begin with.
Pray tell, that it is NOT installed in either of Window's terror-torial domains of \Program file localities. Window's... does NOT like you tampering with files & such, in its... terror-tory.
What all mod wise are you running, besides the basic ones that come along with LSH3...
Are you using either... a 4GB patch with said set up, or using Large Address Aware, to assign the LSH3 SH3.exe access to using 4 GB's of RAM.
All that, off the top of My head... would be very valuable info to know... to be able to even begin to sort out why you are having issues...
of course, it could be, that the mod just won't work with that mod mix. Which is a possibility, NOT to be ruled out... outright.
And.... seeing, as how this issue, is related, to LSH3... would be better asked, in the main thread, specifically for it. Just saying... that is, what it is there, for.
That thread, can be found, here:

Any rate, all the best in getting a resolution to your situation.
