When you've re-installed, did you delete your save folder, whether "My Documents / SH4", or whatever you named it (them), if using MultiSH? Get rid of your save folders and try again. We've found with all the installing / re-installing of the FotRSU mod, that if you leave behind one little thing, it spoils the whole mix, and you are forever finding the issue... Also, I can't say enough good about
Rockin Robbin's SH4 CMS and
CapnScurvy's Win10 LAA SH4 Install. RR's utility will save you all sorts of time in the future, and CapnScurvy's [TEC] has all sorts of detail for the Windows user. Good stuff.
