Bump map failure?!

[virtualfm]

hi there!
im working on a bevcan (redbull-like). to get that bumps on top of the can i created a bumpmap in photoshop and connected it to the object via bump map generator. looks not that bad, but there are some strange artifacts on the bumped object. i made a screenshot (i hope this free web space site works!), so please have a look. i played around with the offsets/position of the bumpmap, but i couldnt get rid of these failures. saving the map in different formats (jpeg, gif, psd) didnt work too.
here's the screenshot:

hmmm... seems like this shitty web space provider doesnt work with quick-links. please copy-paste the url above to your browser.
ok, so if anybody has an idea why these artifact are messing up my bumpmap, please tell me!
many thx in advance! big up, cya

i got this post from coolcalb in the xsibase forum:

as far as i know the bump-map generator is buggy (maybe they fixed it somewhere in ver2.x)

I dont use it. Instead connect it as a normal texture (Texture>ADD)
and in the Diffuse and Ambient mixers in the render tree, go to the wheight tab of the bump
texture and turn it down to zero.. (dont forget to turn bump ON in the texture node)

whats your opinion about that? is that bump map generator buggy?
i'll try that kind of workaround when im home again. which is in about 3 hours. time's runnin' out, so, u think this works?
