outreg2以前还能用，现在不知道为什么突然用不了了，用完以后显示如下，还导致stata内部数据乱码，还得重新导入数据，请问有人知道怎么回事吗


. do "C:\Users\dell\AppData\Local\Temp\STD3f9c_000000.tmp"

.  outreg2 [m1 m2 m3 m4] using DOIB.xls,word replace pvalue
file C:\Users\dell\AppData\Local\Temp\ST_3f9c_000002.tmp cannot be modified or erased;
    likely cause is read-only directory or file nothing to restore could not restore sort order because variables were dropped
