T41 AccessIBM on desktop wants uc.exe

[T400plus]

i managed to damage my working 40gb Hd and I had tosettle with a old 25Gb harddisk
ihad preserved frommy 2373 1HU(it was a 1.4 Ghz cpu 1ith 1 mb cache..).
when i clicked on the accessIbmtoken it says it wants the above filebut after some clicksit
continues with the rest of the options in the program.
I estimated that uc.exe isprobably a driver update program. How do i get it now?.
my warranty gotover in jan 2007.the machine works nicely otherwise.[No big dealas
under warranty i had got the screen changed thrice ,MB atleast once and the cd drive nearly
3-4times[it would read dvd but not cds!] ,it is only a reader].
currently i have a 1.6 pentium M cpu and 1.5 GB memory with this T41 mix .
