Default Jdownloader won't start this am...

...I see "javaw.exe" running and using 13% of my Cpu and using 513 kb of memory...about a week ago I unistalled the latest java and reinstalled the previous verson since I was having crash problems similar to some other posts and that was a suggested solution...I couldn't really see any difference afterwards, however...nothing else has changed...I'm running win7(64) with intel processor...no firewall, no antivirus programs...I saved a "javaw.dmp" file if that helps:

...an addendum...I brought the problem up in a response to another post and "Jiaz" asked how many links I had and what theme I used...I use Jdownloader's default theme...the number of links I'm not sure of but definitely a bunch...I tend to not delete my links after they've downloaded in order to help keeptrack of what has been downloaded and in order to avoid downloading duplicate files...

...darn!...another addendum...I wrote that javaw.exe was using 500 kb of memory -- that should read 500 THOUSAND kb of memory...also, I tried the "JDownloaderNIGHTLY.exe" but nothing changed -- still using around 13% of CPU and 500,000 kb of memory...

try to start jd with following command
java -Xmx1024m -jar JDownloader.jar
from commandline

eg
start cmd.exe
then change to jd folder
eg
cd c:\programme\jdownloader
then the command above

close old jd before doing that (killall java processes)

...okay, first, I just noticed that that the "database.log" file in my config folder is 3 GIGAbytes in size...might that have something to do with it?

...second, I entered "java -Xmx1024m -jar JDownloader.jar" from the commandline as instructed and got this: "java is not recognized as an internal or external command, operable program, or batch file."...

yes thats the cause. 3GB database.log = broken/Damaged database.
you can only try to make it work with increased heap

replace java with
"c:\program files\java\bin\java.exe"
(path may need adapted to your system

also try
-Xmx2048m
as paramter

...yet another addendum...I said I tried "jdownloadernightly.exe" earlier but I think that was a mistake...I think the program just locked up and didn't update...I've tried it a couple of times since and I don't think it's able to update the program in its current condition...it starts and then just immediately disappears...

jdownloadernightly is only the same as
java.exe -Xmx512m -jar JDownloader.jar -branch NIGHTLY

has nothing to do with your database 3gb problem.
you need to run jd with a very high heap (eg -Xmx2048m) in order to load your database and try to make it work.

...thanks for your help...I'm not quite clear what you want me do, however...I opened java via control panel and added -xmx2048m as a parameter to "javaw.exe"...that didn't help...but i'm not sure what you mean when you say "replace java with c:\program files\java\bin\java.exe"...

...well, that's just weird...I opened the database script file (162 mb) with notepad and deleted the lower third so the new file became about 130 mb...and now it's working fine...and looking through the files to be downloaded, I don't see that anything is missing...

maybe some garbage was in database or it was broken and garbage attached to it.
but finally you could fix it.
i suggest to remove finished links from database to keep it clean and small
