Can´t upload or rollback my project

[vega]

hi everyone. I guess this is a generell problem and not a java specific problem, so i post here and not in the java forum.

while uploading changes to my app, eclipse crushed - and with it, the upload of the project.
When i want to restart the upload, it tells me, that i have to use 'appcfg rollback', because the system things that another transaction is still ongoing....

when i use 'appcfg rollback' i get this error:

Unable to rollback:

I fear this might be an error with the proxy-server in my company.... is there a way to rollback the project without touching the proxy-server, which would involve long "battles" with the help-desk?

Changing the Vers-Number allowed me to upload my changes....
will this "going around the problem" result in problems?
