Problem with cycloneIII

Hi,

I went from 10.0 Quartus II to Quartus II 11.0.

a first code that worked fine is now hanging to the point:

timequest timing analysis

sometimes says

Error: Tcl error: error deleting "pos_vel.sta.summary": permission denied

while executing

"file delete -force $summary_file"

invoked from within

"if [file exist $summary_file] {

msg_vdebug "QSTA_DEFAULT_SCRIPT: About to delete $summary_file"

file delete -force $summary_file

}"

invoked from within

"if [is_project_open] {

if {$options(qsf2sdc)} {

post_message -type info "Migrating assignments from quartus_tan"

set value [get_ini_var -nam..."

(procedure "main" line 121)

invoked from within

"main"

(file "c:/altera/11.0/quartus/common/tcl/internal/qsta_default_script.tcl" line 1104)

Error: Quartus II TimeQuest Timing Analyzer was unsuccessful. 1 error, 8 warnings

Error: Peak virtual memory: 225 megabytes

Error: Processing ended: Tue Oct 04 21:18:20 2011

Error: Elapsed time: 00:00:03

Please can you help me,

thank you very much
