problem installing sparks from command line

[eluser]bulmer[/eluser]
...and this is the error I receive when I try to download a spark:

Warning: rename(C:\Users\All\AppData\Local\Temp\/spark-24-1336898497/spark.info,
./sparks/autoform/3.8.1/spark.info): No error in E:\UniServer530_codeigniter\www
\tools\lib\spark\spark_utils.php on line 46
←[1;36m[ SPARK ]←[0m Spark installed to ./sparks/autoform/3.8.1 - You're on fire
!

Only i'm not "on fire", just an empty folder structure...
