SASHIMI thread doesn't address because it is not a SASHIMI issue.
SASHIMI doesn't install anything permanently on your system in and of itself (it just resides on the storage card).
Every change SASHIMI makes to your system is decided by you.
If you give SASHIMI 10 cabs to install and 3.reg files to import then it is doing nothing but that.
I can pretty much guarantee you that if you manually go through the files that SASHIMI is installing and do them all yourself you will have the same problems. If not, then you are skipping something.
Users have reported issues like this before (not specific to your problem, but in general) where they think SASHIMI is the problem but then they realize that they are providing bad files to SASHIMI to process (e.g. a REG file that contains entries that is causing the problem).
I highly recommend doing this manually. If the problem is not there, then you need to go through your SASHIMI directory with a fine toothed comb and make sure there aren't any .reg files or anything that it is importing that is causing the problem.
If you can recreate an issue where anything installed by SASHIMI is causing a problem that isn't caused via other methods (manual, UC, etc), then please let me know.... I've never heard of one.
