There is no reason why multiple separate installs of IC should not be able 
to run on the same server, provided that the machine has adequate resources 
(memory, disk space/speed, processor speed, bandwidth, etc), and that the 
usernames under which the IC installations run do not overlap.  I have 
several installs of IC and MV, for separate virtual domains, running on my 
server without problems; I even have MV3 IC installed and running 
simultaneously for one user (working on an upgrade), they coexist in harmony.

Something specific to your host's server setup is the catalyst in your 
case.  Unfortunately I can't be more help than that.  Beyond verifying that 
the server is adequately equipped, and that you and other IC users on the 
server are not contaminating eachother's sessions or processes somehow (I 
am not even sure if the latter is possible), you just have to decide if 
staying with this current host is worth the effort of going on a quest for 
the solution.  There are numerous hosting alternatives out there.

Good Luck!
