Problem launching SBT Eclipse 9.1sp2 on Linux centOS 5.5

Hello.

I am trying to follow the tutorial about how install Quartus II on centOS from Nios Wiki:

http://www.nioswiki.com/OperatingSys...uartusforLinux

I am using 9.1 sp2 software instead of 9.1 sp1 wich is used in the tutorial.

For that reason, I had to modify the "n2sdk" file. I changed the lines wich had "/opt/altera9.1sp1/" to "opt/altera9.1sp2/".

Quartus II runs fine except for the next message:

"warning: Can't contact license server "1800@localhost" -- this server will be ignored "

I am using Quartus II web edition. For that reason, I don't care about the license.

SOPC Builder runs fine, but when I try to run SBT Eclipse, I have the problem. It runs fine until the wokspace prompt. In that prompt, I have tried many directories, but after that, when the program is loading again, it stops, and appears the message that is shown below:

"An error has ocurred. See the log file

/home/takumikite/workspace/.metadata/.log"

When I open that ".log" file, appears the next text:

See attached for log

I had to cut the text because it has too many characters, but the part of the text that I cut is like the first part of the text:

"!ENTRY org.eclipse.ui.workbench 4 0 2010-11-12 11:31:46.909

!MESSAGE Widget disposed too early!

!STACK 0

java.lang.RuntimeException: Widget disposed too early!

at org.eclipse.ui.internal.WorkbenchPartReference$1.w idgetDisposed(WorkbenchPartReference.java:171)

at org.eclipse.swt.widgets.TypedListener.handleEvent( TypedListener.java:117)

...

..."

This part is repeated many times, until reach the last part:

"!ENTRY org.eclipse.osgi 4 0 2010-11-12 11:46:50.564

!MESSAGE Application error

!STACK 1

org.eclipse.swt.SWTError: XPCOM error -2147467262

...

..."

Could you help me?.

Thank you.
