Problem with temp tablespace

I'm trying to build an index on a 7.3.4.5 system.

I;ve run the following as user "sys":

ALTER USER flink TEMPORARY TABLESPACE TEMP ; ALTER USER flink DEFAULT TABLESPACE TEMP ;

Yet, when i try to create an index as this suer, I get.

ERROR at line 2:
ORA-01630: max # extents (1) reached in temp segment in tablespace INDEX2_TS

The _index_ is declared to be in IDEX2_TS, but this message, says I'm out of TEMP space.

What's going on here?

I think I have spce for this index in the specifed tablespace:

TSPACE TOT_MB ORA_BLKS TOT_USED PCT_USED --------------- ---------- ---------- ---------- ----------

Here's the index ceate statement:

CREATE UNIQUE INDEX P_STA_PUMP4_2

        ON P_STA_PUMP4
		(
		  DSTAMP
	  )
	  TABLESPACE INDEX2_TS 
	  STORAGE (
				  INITIAL 79000K
				  NEXT 0K
				  MAXEXTENTS 1
				  PCTINCREASE 0
			  ) 
			  PCTFREE 1;
