skype on acer aspire one

linux newcomer askes for help...
I installed skype 2.0 on my acer aspire one 150 linpus netbook a few month ago.
The installation was easy and I had no prblms
Cause of some instability I wanted to upgrade to skype 2.1
I downloaded the rpm of skype 2.1 and tried to install without having deinstalled version 2.0 before...
Installation was quit with comment "successfully installed".
Unfortunately I cannot start skype. I can see the icon on right mouse click and network but it does not start. I tried to reinstall former version that worked but did not succeed to find the downloadlink (skype-2.0.0.72-fc5.i586.rpm) again.
:-( :-(
If there is anybody knowing a hint I would be glad... thanks!

Two days later I tried this with sm file and fortunately it worked but nowbody should ask me how I did this..
Eventually somebody can give me a good advice where to find a good intro for linps or linux not to continue being a stupid MS-coming man any longer :-D :-D

 

The older versions can only be obtained from skype if you register as a developer. Either install the static binary file on the download page or get your old version from here..

extract and click on the .sh (shell script)

 

FIt would be handy if this worked but for Skype &FF£ this brings up message can' recognise archive format and exits
