help,,,wont load

[buddha95]

Game crashed yesterday.
emptied out all.
reinstalled game 1.4
reinstalled mods.
it worked, played ,,,, had fun
went to ubisoft and downloaded 1.5
( it did it automatically and didnt ask for my key) (i had it before the crash)
game wont finish loading
removed all mods in generic enabler but game alone wont finish loading,
bar goes 80% across then a "ting" tells me it has failed

what to do???????????????????
i would hate to have to erase everything again ( it took 5 hours this morning)
