Mmkay...

well first of all, welcome to the forums.
Secondly, this thread's topic's five words are more informative than the error report (which that monstrosity apparently is supposed to be) you posted. Is that a Microsoft error report or what?

We'll definitely need a bit more specified information to solve the problem...

1. Are you running Silent Threat on retail Freespace 1 as a campaign, or are you using FS2_Open engine with FSPort mod (including Silent Threat campaign) selected?
Some of the version numbers included in that wall of letters up there seem to suggest you're using retail FS1, in which case it would be no wonder that Silent Threat crashes because it was rather buggy as far as I know.
2. What kind of system are you using? Operating system is rather obviously Windows XP, but other specs can't be harmful to tell either. Of specific interest are the graphics card, the amount of installed system memory and the CPU, in right about that order of importance.
3. In what kind of situation does Silent Threat crash? As soon as you select the campaign? As soon as you get into first mission? Randomly?

In certain mission, when something happens?
Posting this information should be a good start when the Powers that Be notice your topic and start digging to it...
