Right. thanks for the quick reply. Currently I haven't installed the SMIM Update to 1-87 from 1-76 optional file, since I have reason to believe it's not actually needed with this version. However, I'm taking my sweet time with installing STEP, therefor I'm confident clarification on the issue will be provided while I work my way down the list.
SMIM has recieved an update and the latest version since the 9th of August is SMIM 1-88. As a layman, I'm not sure wether or not to still follow STEP to the letter.
