Hi, I've just re-activated your LZX download.
The thing with the missing/corrupted files is very strange and it most likely explains the general instability you're experiencing.
I just checked the content of the LZX archive and I can confirm that both Lamp.mcc (29,149 bytes) and Lamp.mcp (12,156 bytes) files are there.
Please check the size of your downloaded LZX archive. It should be 345,620,139 bytes. Also make sure you used regular LZX
to uninstall the archive according to the Quick Guide
, page 5. Using some other unarchivers might result in an corrupted extracted content.
